Beginning: 16.02.2025 – 9.00 AM Impact: [MOBILE] Disruption affecting e-SIM porting Dear customer, dear partner, Over the past few days, Proximus has been experiencing technical issues affecting the porting of mobile lines to virtual “e-SIM” cards. A fix was implemented last weekend; however, it does not appear to be working as expected. This may cause disruptions in e-SIM mobile activations and, consequently, extend porting timelines or even render the mobile number inaccessible for several hours. Therefore, we kindly ask you to temporarily prioritize mobile porting on physical SIM cards rather than on e-SIMs. Only e-SIM porting is affected. New number orders on e-SIM are functioning properly, as are porting requests on physical SIM cards. We expect a technical correction within the next few days and will inform you as soon as the issue has been fully resolved. Best regards; SEWAN technical team

Sewan Live Belgium — Mon, 01 Dec 2025 13:38:00 +0000

Cher client, cher partenaire, Il y a deux mois, nous vous avions informés que, suite à de nouvelles contraintes régulatoires, notre fournisseur avait dû suspendre temporairement l’attribution et le portage des numéros au Luxembourg. Depuis, la situation s’est encore complexifiée, au point de compromettre la continuité de ce service. Après analyse, nous avons du prendre la décision d'arrêter l'exploitation de numéros luxembourgeois au 31 décembre 2025. Jusqu’à cette date, nous garantissons le maintien du service pour l’ensemble des numéros actuellement actifs. Au-delà de cette échéance, le service sera totalement interrompu. Si vous souhaitez malgré tout continuer l'exploitation des numéros luxembourgeois actuellement fournis par Sewan Belgium, veuillez vous rapprocher d'un opérateur local dans le but de migrer vos numéros. En résumé, cela signifie que : L’attribution de nouveaux numéros au Luxembourg reste suspendue, Aucune nouvelle demande de portage entrant vers le Luxembourg ne peut être acceptée, Le service existant est maintenu jusqu’au 31/12/2025, après quoi les numéros luxembourgeois encore présents sur votre compte seront supprimés. Important : Dans le cas où vous mettriez à disposition des numéros luxembourgeois à vos clients (et non pour votre usage propre), vous êtes légalement tenu de vous conformer à la réglementation locale. Pour continuer vos activités au Luxembourg, vous devez disposer d’une licence ILR, même dans le cas où votre fournisseur est lui aussi enregistré à l'ILR. Plus d'informations ICI Nous vous remercions pour votre compréhension. Bien cordialement, L’équipe Sewan

Sewan Live Belgium — Thu, 18 Apr 2024 18:00:00 +0000

Dear customer, As you know, your IT security is at the heart of our daily concerns. Therefore we would like to inform you that we have recently been alerted by the Belgian telecoms regulator (BIPT, the Belgian Institute for Postal Services and Telecommunications) to a suspected identity theft fraud, more commonly known as the "President scam" or "fake bank transfer orders". Several press articles have already reported on this new modus operandi. This form of fraud involves the sending of fraudulent transfer requests by ill-intentioned individuals posing as members of your company or legitimate suppliers. These scams can result in significant financial losses. Sometimes, these fraudsters manage to take control of one or more mailboxes within the targeted company, then send their invoice on behalf of a company decision-maker to reinforce the credibility of their pitch. To protect yourself, we advise you to be particularly vigilant when receiving transfer requests, systematically verifying their legitimacy. Be sure to validate all transfer requests with reliable sources, using verified communication channels and confirming transaction details with the parties involved. Please do not hesitate to contact our Customer Success team if you have any doubts about a transfer request or if you would like further advice on how to prevent fraud. Your security is our priority. We are more than ever at your disposal to help you protect your interests. Sewan Team

Dear Partner, a Fortinet OS security breach has been detected in our Fortinet Firewall platforms concerning the SSL-VPN. This is an "N-Day" vunerability, i.e. a global and major breach that impacts all customers on a very large number of deployed versions. Fortinet has issued a statement on the subject, on a dedicated page. What does this mean? The detected breach is a vulnerability in the Firewall SSL VPN process, enabling a potential attacker (a Hacker) to execute unauthorized code or commands in the system. How does Sewan react to this vulnerability? As soon as the breach was detected, the security teams in Sewan's Technical Department took Fortinet's actions into account and planned an update of all OS versions deployed among Sewan's partners and customers. We recommend that you temporarily disable SSL VPN on your Fortinet interface while our teams perform the upgrade. Update planning : • Cluster 1 : 09/02/2024 PM • Cluster 2 : 11/02/2024 PM • Cluster 3 : 11/02/2024 PM • Cluster 4 : 09/02/2024 PM • Cluster 6 : 11/02/2024 PM • Cluster 7 : 11/02/2024 PM • Cluster 8 : 09/02/2024 PM • Cluster HDS : 09/02/2024 PM This should only cause a small cut, in the worst case.

Technical Incident Report Incident Overview Date of Incident: Thursday, 7th December Services Affected: VoIP Systems - v5 & Sophia Impact: Some customers experienced one-way audio during reinvite scenarios. Description of the Incident On the morning of December 7th, we received reports from several customers experiencing issues with our end-to-end VoIP system. Specifically, during reinvite scenarios, the called party was encountering one-way audio issues. Our monitoring systems also detected empty RTP (Real-Time Protocol) packets, which was an unusual occurrence. Initial Investigation A team was immediately assembled to investigate the issue. The following steps were taken as part of the initial investigation: Verification of Customer Reports: We confirmed the reported issue by simulating reinvite scenarios and observed the one-way audio problem. Analysis of RTP Packets: Examination of the RTP packets revealed that they were empty, which was consistent with the one-way audio reports. Check with External Parties: We reached out to our external partners and telecom providers from whom the calls originated to ascertain if there were any recent changes or issues on their end. Internal Systems Review: Our team conducted a thorough review of our internal systems. We verified configurations and recent change logs to rule out any internal updates that could have caused the issue. Root Cause Analysis: Despite extensive investigation, no recent changes or anomalies were found in both our and our partners' systems that could directly be linked to the incident. This led to the conclusion that the issue might be related to the way reinvite scenarios were being handled in our VoIP infrastructure. Resolution and Recovery To mitigate the issue and restore service for the impacted customers, we made the following changes: Re-invite Behavior Modification: We temporarily adjusted the re-invite behavior in our VoIP system. This change was specifically targeted at the customers who were experiencing the issue. Result: After implementing this change, the functionality was restored, and customers reported the resolution of the one-way audio problem. Post-Incident Actions Monitoring: Enhanced monitoring has been put in place to closely observe the reinvite scenarios and RTP packet integrity. Further Investigation: A team has been assigned to continue investigating the root cause of the empty RTP packets in reinvite scenarios. This includes a deeper dive into the interplay between our systems and those of our external partners. Customer Communication: We have reached out to all affected customers, explaining the incident and the steps taken to resolve it. An apology for the inconvenience and assurance of our commitment to service quality were communicated. Conclusion The incident was resolved on the quickly after it was reported, with minimal long-term impact on our customers. We appreciate the patience and cooperation of all parties involved and remain committed to providing high-quality, reliable VoIP services.

After the change, we performed several tests to confirm the maintenance. The redundancy has been confirmed with no error. On the same date, at 9:02 AM, we started to receive complains on specific VPN access. Our team started to investigate and found performance issues with one of our switch ports. This problem was handled and solved at 11:00 AM, but without better conclusions. From 11:00 AM to 1:00 PM : As only specific issues were spotted, we continued to check configuration on our side. After several checks, we found that it could be due to BGP AS bad announces with PROXIMUS AS and our upstreams. We could confirm that with our diagnostic tools, with different results depending on different providers. Some worked, so did not. After that, we implemented specific configuration to hide PXAS AS with SEWAN AS. This result in a progressive improvement of lines speed, until 4:46 PM were we confirmed that the situation was back to normal. Corrective maintenance will be foreseen in the coming days in order to prevent this type of issue from occurring in the future. Please accept our apologize for the inconvenience it may have caused.

Dear customer, dear partner, We would like to inform you that mobile customers are being targeted by cybercriminals. These cybercriminals attempt to obtain access to personal data by installing a piece of malware on the End-User device. Besides the "usual" SIMbox, FluBot malware is currently very active. It spreads via SMS through contacts on the infected phone, with the ultimate goal to steal bank details and passwords from their devices. How does it work? FluBot pulls off a rather audacious bluff by warning users that they have been infected by… FluBot. It offers to install a (fake) security update to "protect" the user from FluBot. The malware goes so far as to explain how to disable the phone's security to install the fake update. As from the moment the fake security update is installed, the malware actually infects the device. In case you experience such practice, please immediately report to our support team.

Sewan Live Belgium — Thu, 23 Sep 2021 14:57:00 +0000

Dear customer, dear partner, As some of you unfortunately already experienced, recent changes are causing troubles for Luxemburgish VoIP terminating to end properly with Luxemburgish CLI. After several investigations through multiple international carriers, we could discover that a general call barring have been applied by these carriers to not allow calls from Luxembourg to Luxembourg to go through a non-Luxembourgish network. This results that calls issued with Luxembourgish number to a Luxembourgish number will no longer be possible if they are transiting through a non-Luxembourgish carrier, while calls issued with a Belgian number to a Luxembourgish number will perfectly work. The legal explanation received is the following : “Direct suppliers advised that they observed massive spam calls from different rotative fakes numbers starting with different Luxembourgish prefixes like +352 3xx xxx or +352 9xxxx therefore a blocking has been implemented. Also, they advised that calls from Luxembourg with Luxembourgish fixed A-numbers should not be routed via international carriers due to spam and fake call situation.” After multiple exchanges, we can confirm that at no moment we, Sewan, is responsible of this situation, but is a victim of it. As we think this situation is a completely non sense, we are at this very moment trying to find a practical way to work with our suppliers in order to allow our legitimate traffic. At this moment, we cannot confirm that we will find a commercial agreement. Please note that this situation is general and affect the major international carriers with whom we work. Sewan Team

Beginning: 17.08.2021 – 9.02 AM Ending: 17.08.2021 – 2.47 AM Impact: Degradation of mobile service -------------------------- UPDATE ***** 24.08.2021 – 5.00 PM Please find below the full incident report received by Proximus. Executive summary - On Tuesday 17/08/2021 at 08h55, Sewan MVNO’s end-user were unable to make calls from Belgium to Belgium and when roaming abroad. Customer impact - End users were not able to make outgoing calls from 08h55 until 14h45 from Belgium to Belgium and calls in Roaming Usage type not impacted by the issue: - Outgoing calls from Belgium to international destination - Outgoing calls to the voice mail - Call forward to the Voice mail - Incoming calls - SMS traffic - DATA traffic Detail affected customers - In total, 3684 call attempts were unable to be performed Detailed Timing - 08h55: First unsuccessful call detected on the platform - 09h00: Email sent by Sewan to our Operational support -> quick reaction by the partner - 10h09: Email escalated to the SUPPLIER support team and Proximus Mobile Engineering SPOC - 10h17: Email answered by SUPPLIER support team -> quick reaction - 11h45: Usage monitoring Voice disable for all contacts but not solving the issue - 13h30: Fall-back plan scenario discussed with technical team to unlock the situation and have a B Plan to allow the calls from Sewan end users, waiting final fix on the SUPPLIER platform - 13h38: Service usage monitoring Voice was completely removed, and all rules still present in the table were cleaned - 14h18: Fall-back plan analyzed by technical SPOC in view of possible implementation. Difficult part was to apply the fall-back only on the Sewan sub IMSI range. - 14h45: Unused regions were fully cleaned on SUPPLIER side and alarms stopped - 14h54: SUPPLIER support confirmed changes applied and issue to be solved -> last alarm raised at 14h49, as from 14h50, impact was cleared out - 14h58: fall-back plan ready for implementation by Ops team (but in the meantime, issue also solved on the SUPPLIER platform, so implementation was stopped) Root cause - The root cause for the issues was that a region was deleted that was still in use for a specific sum plan. With Service Usage Monitoring enabled, and full authorization for the session in question, SUPPLIER platform performs the SUM check to verify whether the subscriber, who requests services, needs to be monitored. - This SUM check happens before the connection with the other party is established - The service usage monitoring rule with region 16 was still existing in the table. - But due to the missing region, the authorization of the session could not be completed and hence the session was rejected. Future actions - Improve ticket creation and prioritization. In case of service interruption impacting all customers, L1 ticket should be created. Light MVNO could call the ICT desk after creation to get ticket prioritized on L1, high priority. Process improvement will be taken up by a process manager. - When a big update is needed on the setup/config, ChangeRequest will be created on SUPPLIER side to analyze the changes and possible impact on the platform => small impact on implementation time At SUPPLIER, a change request is raised to modify the logic in such a way that a delete of the region should be interrupted if it is in use in any configuration. ( Database modification: Foreign Key Constraint) Complete Fall-back plan description will be created so everybody knows how to implement on a very quick mode (Sub IMSI only) - Feedback loop towards partner has been inefficient or even absent. A process will be set-up in place with 1 main escalation/operational manager to handle the communication towards external partners. This will allow operational team to focus on resolution while providing live status to operational manager for communication purpose. -------------------------- UPDATE ***** 17.08.2021 – 3.30 PM Please note that the mobile service has been successfully restored by Proximus at 2.47PM today. The situation is still in investigation. -------------------------- Dear customer, dear partner, since 9.02AM today, we experience partial outage on our mobile service. This results that all outbound calls to Belgian numbers are not working. 3G, 4G, 5G, SMS/MMS, inbound calls and international calls are working fine. After investigation, we can confirm that Proximus is responsible for this outage, and are putting all necessary efforts to solve their issue. At this moment, all our team is mobilized to support them in their fast resolution. No ETA has been communicated at this stage. Our apologies for any inconvenience this may have caused.

There were scenario’s in which a loop was not detected, which resulted in quickly growing rtp stream. This could quickly be resolved case-by-case, by finding the culprit stream and kill it. Yet, this was not a long term solution, as it gave unexpected issues on the platform, like slow responses on SIP messages. While debugging this, the quickest way to come back to a full resolution, was a restart of the registrar, which broke sip registration for a brief period of time. (until next registration) With the software team of this product, we were able to receive an updated version ending of last week, which was rolled out on one gateway so far. The first results are very promising, the loops do not occur. We are planning to upgrade all our media gateways to this version. Our apologies for the inconvenience.

This resulted for some customers which were routed to us over several IP Transit providers in calls being cut, registrations being lost and bad quality in the calls. After checking with two of these carriers, the problems were confirmed to find their origin in Packetloss in one of the major backbones in Brussels, due to a very high volume of traffic they had to cope with. At 5.30PM, we were informed the problems were totally resolved at their side. Our apologies for any inconvenience this may have caused. Best regards; SEWAN technical team

Beginning: 22.01.2021 – 9.46 AM Ending: 22.01.2021 – 2.35 PM Impacts: Outbound mobile calls partially unreachable Dear customer, dear partner, Please note that today one of our upstream mobile carrier was, without any valid reason, blocking a significant part of our outbound Belgium mobile traffic. As we have in place multiple failover scenery, most of the calls blocked were mitigated toward other carriers. Nevertheless, part of the traffic sent to the faulty upstream carrier was sending back to us an incoherent error code (403. Forbidden) which we (as all other telecom carriers) consider a user based return code (meaning a code stating that the recipient of the call does not want to accept it). Therefore, this wrongly given code made our system consider as a normal behave and, therefore, did not trigger failover routings. When we discovered this double fault, we temporarily adapted our routing, and raised an emergency case toward the upstream carrier for investigation. Best regards; SEWAN Technical Team
