No GPRS connection with some devices

Hello John
After checking further, I believe the modem is using SIM with different network identity than 00101 that is configured in the BTS.
To solve this:
1. Try SIM with the network identity 00101
2. Enable data roaming in the modem.

Hello John,
Having the MS in home network or roaming network depends on both the SIM and the network
if the network identifier matches , the MS will believe its connected to its home network.
In your situation, there is a mismatch , so the telit modem thinks its in roaming mode and GPRS for roaming needs to be enabled with AT commands.
Like in mobile phones, when you switch to roaming , you need to activate data roaming option from the settings.
As when you check registration from AT , you can see it thinks its in roaming (5).
Thanks,
Nour

hi nour,
i can't figure out how to enable roaming on telit, but i can tell to you that with osmocom i had test network as yate (100 01) and it works with the same SIM as now.

Hi John,
You are welcome :)
Can you please try:
AT+WGPRS=<mode>[, [<parameter>] [,<parameter2>]
Mode 7: Automatic GPRS roaming inter-operator (the mobile equipment automatically reattaches itself to the network and reactivates its PDP context by changing the operator when reaching border areas. Only <class> is used.
<parameter> Requested operation for <mode> (except for <mode>=4 and 8)
0 Disabled
2 Enabled
Then try to register and attach again.
Thanks,
Nour
