Hologram Outage History

We are currently investigating a possible service disruption affecting Global-3 profiles (ICCID prefix *89464) and their ability to create and maintain data sessions. We are working with our upstream providers to diagnose and resolve this issue, and will share more details as more information becomes available.

We are currently investigating an issue where our Global-3 profiles cannot send or receive SMS messages when connected to AT&T. These same profiles do not have any issues with other networks. Data transfer remains unaffected. All other profiles remain unaffected.

We are continuing to investigate this issue.

We are currently experiencing a partial outage on our Global-2 profiles when performing some eUICC operations. We are actively working with our upstream partners to get this back to normal as soon as possible. Connectivity remains unaffected on Global-2 profiles. All other profiles remain unaffected along with their eUICC operations.

We are continuing to investigate this issue.

We are investigating reports of devices on the USA-2 profile losing connectivity in the United States, beginning at approximately 2:10 PM CT (19:10 UTC) on September 3, 2026. This may also affect data roaming on the Verizon network for Global profiles.

We are investigating an increase in signaling failures on 2G and 3G networks with our Global-3 carrier partner. Impact appears concentrated in North and South America and affects several operators across multiple countries. Affected devices may fail to attach or register or may see repeated attach retries on 2G/3G. Devices attaching over LTE, LTE-M, or NB-IoT are not currently affected. The disturbance began at 2026-08-27 20:30 UTC.

We are seeing that traffic on the following networks may be impacted by this issue. This may not be an exhaustive list. Affected devices may fail to attach or register or may see repeated attach retries on 2G/3G. Devices attaching over LTE, LTE-M, or NB-IoT are not currently affected. Canada, Bell Canada, Rogers Canada, TELUS Mexico, Telcel Mexico, AT&T USA, Verizon USA, T-Mobile USA, AT&T Jamaica, Flow Thailand, AWN India, Vodafone

We are currently investigating an issue where Conductor API services are unavailable, impacting eUICC operations on active SIMs. Non-Conductor related API endpoints remain unaffected.

We are currently investigating the issue. This does not impact connectivity for activated USA-2 profiles and only impacts the activation of new USA-2 profiles.

There is currently an issue affecting session reporting in the dashboard. Updates for new sessions will not appear in the dashboard until this issue is resolved.

This issue has been resolved

We are aware of and investigating an issue impacting the ability to change SIM state on G3 profiles. We've engaged our providers and will provide further information as soon as it becomes available

Hologram Engineers have identified an issue with the usage consumer from one of our carrier partners. We are investigating a fix. Connectivity is not affected. This is only impacting G1 Carrier Profiles starting with 8944*

We are currently investigating a reported issue on our Global-2 profiles (ICCID prefix 89357*). Some devices might have trouble establishing or maintaining sessions. We are actively working with our upstream partners on a resolution and we'll provide updates as more information becomes available.

We are currently experiencing a backlog causing delays in SIM state changes for Global-1 profiles. Customers may experience longer than expected processing times when activating, deactivating, or pausing SIMs. We are unable to provide an estimated resolution time at this point, but we are actively working to clear the backlog. Cellular network connectivity and other API services are unaffected.

We are seeing intermittent connectivity with some of our US2 profiles. Verizon is currently investigating the issue. All other profiles remain unaffected.

We are experiencing a delay on SIM card administrative operations (activations, plan changes, state changes) on our Global-1 profiles. Operations done through the Dashboard and API are impacted. Connectivity remains unaffected. All other profiles remain unaffected.

One of our partners is experiencing issues that is affecting the ability to connect and transmit cellular data. Hologram is investigating an issue affecting 4G services globally, it may cause problems attaching to 4G networks and using 4G services. This only is affecting SIMs with the 8946* prefix.

Verizon is currently experiencing an issue where data usage/reporting is delayed on US2 profiles (Verizon-native). We are working with Verizon's team to get this resolved and the usage backfilled. We will provide updates as soon as we have further information. Reporting on all other profiles remains unaffected. Connectivity remains unaffected on all profiles.

We are currently investigating an issue with restoring the API services post-maintenance. We are working to restore services as soon as possible.

One of our upstream network partners is experiencing an outage affecting new registrations on their 2G, 3G, and 4G/LTE networks. We have notified the partner and are working with them to resolve this issue. This outage only affects SIM cards with the ICCID prefix 8935*.
