EHS5 Modem: TCP service state 6 - PDP Problem | Thales IoT Developer Community

November 23, 2017 - 7:30pm, 1260 views

Hi,

I'm using several SIM with no error, when I'm using Telit and only for first time after replacing SIM from other vendor I get result of SISI: 0,6 checking with ^SISE 0,94, "PDP: connection failed".

After reset telit sim start to works normal with no farther issues.

Please try to help solve this issue ...
