We are encountering a cellular connectivity issue where our BORON BRN310 devices are struggling to maintain a stable connection, resulting in excessive cellular data usage.
We are situated in Rwanda, we have 15 devices deployed across the country, with 10 of them currently online. These devices were deployed in August of last year, utilizing embedded SIM cards on Boron BRN310 devices. Since their deployment in August, we haven't faced any issues until the period between the 19th and 21st of March, during which we began experiencing connectivity problems. We received alerts indicating that some devices are not sending data to Ubidots. As we continued seeing the fluctuation of online and offline statuses on several devices, we decided to inspect the Particle console for any anomalies, but found everything to be unchanged.
On the billing page, we noticed a significant increase in data operation, and cellular usage surpassing 100MB. Consequently, our service is scheduled to be paused on April 4th. This has never happened before from when the devices were deployed.
Attached is a simple analysis illustrating the data operation, and cellular usage on 4 of those devices.
Can this be caused by the 15th March reported connectivity incidents in Africa? Are there some changes that were made on the Embedded SIM card on BRN310?
Looking forward to your assistance regarding this issue.
Thank you for unpausing our service. They are back online. Could you please clarify if the unstable cellular connection might be related to reported incidents on March 15th or any changes made to the Embedded SIM card on BRN310?
No changes have been made to any Particle SIM cards.
Connectivity issues typically cause devices to use more data - the more frequent the connection attempt, the higher the usage. We believe this is related to the incident and nothing more.
