Failure to receive IP address since 12-Sep-2018


Abruptly yesterday our devices using SIMCOM 7000E and uBlox SARA-G350 cellular modems started having issues receiving IP addresses from the UK 2G cell networks. We can see them connecting to a network, but sometimes not being allocated an IP address.

This was a non-issue for us up until yesterday, but since the 12th it is happening to multiple devices, but not all of them. Is anyone else seeing similar issues?


Hey @iainwoolley,

Can you please email with the SIM numbers of the devices that are giving you issues.

I want to check our back-end to see if there is anything we can spot.
