DESCRIPTION:

While travelling through Belgium and France, I noticed I didn’t have an internet connection with my german sipgate SIM which, as far as I remember, is quite picky about the correct apn

STEPS TO REPRODUCE:

2.travel to Belgium or France
3. Try to establish a data connection on any of the networks

EXPECTED RESULTS:

data connection will be established

phone tries to connect, changes from connection activated to established, but only for tenths of a second, stays at activated instead if connected after that

ADDITIONAL INFORMATION:

Putting the sipgate SIM in slot 2 instead makes it work fine, connection is established immediately. A german prepaid vodafone callya SIM works fine in both SIM slots.
