Please HELP: old good TC35i not working with a MVNO ??? | Telit Cinterion IoT Developer Community

Hello

Postemobile is an italian MVNO of Wind. They share the same MNC/MMC (22288). It's not simple roaming!

Using the old good TC35i the registration fails as the gsm tries to connect to 22288 as Wind (I WIND).

So if I try:

at+cops=1,2,22288

the registration fails as 22288 is primrily seen as Wind and they reject the registration of postemobile sim card.

If I try:

at+cops=4,0,"POSTEMOBILE"

it gives me a syntax error (?). Where am I wrong? What can I try?

Please also notice that  the same sim inside very old siemens and nokia phones work great.

Thanks
