Update - Smart Meter has provided Validic with the following update on recovery progress.
Over the past 12 hours, approximately 8% of the remaining affected devices have successfully recovered, reconnecting and transmitting data, including observations captured during the outage period. Recovery is continuing, though gradually.
Smart Meter has noted a delay in receiving a tower-level signaling report from their carrier partners. This report is expected to allow Smart Meter to differentiate between devices that were truly impacted and those that simply have not been used, generate an accurate list of devices impacted at any point during the outage, and identify which devices remain impacted versus those that have already recovered. Once received, Smart Meter will correlate it against the existing list of potentially affected devices and devices that have already reconnected. Smart Meter has indicated they still expect to receive this report.
Smart Meter confirms no data loss is expected; all readings will be delivered once connectivity is restored. Continued device usage is important, as each transmission attempt increases the likelihood of recovery. A battery reset can force a fresh network acquisition and may help expedite recovery for individual devices, though it is not universally required.
Validic's platform continues to operate normally. We will post further updates as Smart Meter provides them.

Update - Validic received an updated status from Smart Meter regarding the ongoing carrier network issue affecting iGlucose devices (originally reported on our trust page on April 20). Smart Meter has asked us to relay the following. All information below originates with Smart Meter; Validic is sharing it for context.
Recovery Progress:
Smart Meter continues to see steady, encouraging improvement across the carrier network, with recovery progressing in a positive direction.
- Over the last 12 hours, the number of affected devices has dropped by approximately 11%.
- Both natural network correction and targeted mitigations are working as expected.
- Progress remains gradual, but the overall trend is clearly moving in the right direction.
Operational Notes:
- No data loss is expected. All readings will be delivered as connectivity is restored.
- Continued device usage is critical. Each transmission attempt increases the likelihood of successful recovery.
- A battery reset can force a fresh network acquisition and may help expedite recovery, though this is not universally required.
What to Expect Next:
Smart Meter expects continued improvement over the coming days as:
- Downstream networks complete routing corrections, and/or
- Devices receive and apply updated connection profiles.
Validic will continue to monitor and relay updates from Smart Meter as recovery progresses.

Update - Validic received the following update from Smart Meter regarding the carrier network issue affecting iGlucose devices.
Recovery status:
Smart Meter continues to see a gradual recovery across affected devices, with less than 2% to 3% of devices potentially still impacted.
Carrier escalation:
Smart Meter does not yet have a firm ETA from their carrier partners for full resolution, but is actively working to escalate and apply pressure across all involved parties. Given the complexity of the ecosystem spanning MVNOs, MNOs, and underlying national and regional carriers, resolution requires coordinated action across multiple networks. Smart Meter has identified the responsible parties, and formal incidents are open within their respective systems and are being actively worked.
Affected device list:
Smart Meter is actively analyzing log data from the investigation and has committed to providing a list of affected devices no later than the morning of Wednesday, April 22nd, and potentially sooner as the analysis is completed.
Operational guidance from Smart Meter:
- No data loss is expected; all readings will be delivered as connectivity is restored.
- Continued device usage supports recovery, as each transmission attempt increases the likelihood of success.
- In select cases, a battery reset (remove batteries, then reinsert them and test) can force a fresh network acquisition and may help expedite recovery, though this is not universally required.
Validic will continue to relay updates from Smart Meter as more information becomes available.

Monitoring -
A subset of Smart Meter iGlucose cellular devices is experiencing delayed or intermittent reading transmissions due to a carrier network disruption upstream of Validic. Smart Meter has confirmed the event began Thursday, April 16 (8-10 AM ET) with a hardware failure in the underlying carrier network, followed by lingering DNS caching behavior in certain roaming operator networks within their MVNO.
Scope
- Smart Meter estimates roughly 2% of their device fleet (~5,659 active devices) is affected.
- Validic's platform is operating normally. Ingestion, API, and push services are not impacted.
Patient impact
- Readings are queued on the device and are not lost. Smart Meter devices use store-and-forward.
- Affected patients may notice delayed syncs or may need to take a reading more than once before it transmits.
- Once connectivity is restored for a given device, queued readings backfill automatically. Clinicians may see readings arrive with a start/end date earlier than the created_at date; this is the backfill behavior, not duplicate data.
What Smart Meter is doing
- Pushing updated eSIM profiles to steer affected devices to unimpacted network paths. First reading after a profile update may intentionally fail; the next reading should succeed.
- Working with their carrier partners to obtain a definitive ICCID list of impacted devices.
- Recovery is trending steadily upward as DNS TTLs expire.
What Validic is doing
- Monitoring Created Records volume for Smart Meter / iGlucose. No broad drop-off observed on the Validic side.
- We will update this incident as Smart Meter provides updates toward the full recovery
What Validic clients should be doing
- If a patient reports that smart meter reading hasn't synced with the client's application, then ask the client to take a few more readings on the device. Smart Meter has confirmed that affected devices may need 1-3 reading attempts before the device successfully transmits to the Smart Meter cloud (and from there to Validic). If the device still is not syncing after several attempts, Smart Meter's eSIM profile update may not have propagated yet; additional attempts over the next several hours should resolve it. No readings are lost in the meantime - devices queue data locally and backfill automatically once connectivity is restored.
Reach out to Validic support at support@validic.com if you have any questions. At the moment, Validic is unable to identify which users were affected and which were not. We will update this post if that changes.
