Modem offline?

Due to issues with transition of some customers services, we are sending out replacement sim cards to any customers who are offline or having connection issues.

Dear Valued SardisTEL Customer,

We hope this message finds you well. Today, we have important news to share regarding SardisTEL’s recent acquisition by Alternative Broadband Solutions, Inc., effective February 1st, 2024, and a specific service update that may impact a subset of our customers.

SardisTEL Acquired by Alternative Broadband Solutions, Inc.

We are excited to inform you that SardisTEL has been acquired by Alternative Broadband Solutions, Inc. This strategic move is aimed at enhancing our service offerings, expanding our coverage, and introducing innovative solutions to better serve you. Our teams have been working closely to ensure a seamless transition and to elevate the customer experience. While our initial plan was to announce these changes on March 1st, 2024, following the full migration of our systems, circumstances have prompted us to communicate with you sooner.

Service Continuity for Verizon and T-Mobile Users

We are pleased to confirm that SardisTEL customers utilizing last mile connections through Verizon Wireless or T-Mobile will not experience any service disruptions. Your connection remains stable and is not at risk of any issues related to the acquisition or system integrations.


Potential Service Impact for AT&T Last Mile Connection Users

Unfortunately, we have encountered unexpected challenges with AT&T’s cooperation in the transition process, which may affect SardisTEL customers using AT&T towers for last mile connections. There is a potential for temporary service outages over the next 2-3 days.

For our customers using AT&T towers for last mile connections, we want to be upfront about the possibility of service disruptions in the coming days. This potential arises as we process connections, system registrations, and other critical items through AT&T's systems. Specifically, a number of LTE and 5G connections are scheduled for connection authentication events on February 8th. Unfortunately, AT&T has not yet completed the necessary data migration on their end. This incomplete migration poses a risk that SardisTEL devices may be unable to re-authenticate on the AT&T network or establish a connection to the SardisTEL core exit nodes.

Our teams are working diligently with AT&T to expedite the migration process and ensure that your service remains uninterrupted. However at this time, AT&T engineers have decided to go home for the night vs. stay and resolve lingering issues. This will almost certainly cause issues beginning tomorrow morning, Thursday February 8th 2024. Our teams will be online 24/7 but we are not able to do anything without AT&T completing their work.

Our Actions to Address the Situation

Please be assured that we are fully committed to resolving these challenges with AT&T as swiftly as possible. Our teams are monitoring the situation closely and are prepared to take all necessary steps to minimize any potential impact on your service.

How to Stay Informed

We understand the importance of reliable service and apologize for any inconvenience this may cause. We are committed to keeping you updated on our progress and any developments. For the latest information, please visit our website and check your emails regularly.

If you encounter any service issues or have concerns, please contact our customer support team for assistance. We are here to support you through this transition and address any questions you may have.

Thank you for your patience and understanding during this period of change. We greatly value your trust in us and are dedicated to delivering the quality of service you deserve.

Warm regards,

The Teams at SardisTEL and Alternative Broadband Solutions, Inc.
