I see that the solomo thread has 1500+ posts, so may take some time to read
Are the difficulties in certain countries constant or variable, and has there been discussion of whether or how this might depend on the roaming agreements of what appears to be the other country ID on the SIM card, or maybe added by Materna/vistream themselves?
Or perhaps the problems are that the SIM never registers on the network? I had this to begin with, until Sunsim told me that on some phones the PIN should be prefixed with a 1 or 2: 1xxxx in Germany; 2xxxx roaming. Since then I've also found a SIM menu setting that reboots into the other mode.
