There are at times problems where you choose an allowed network and it won't fail but it won't connect either. Normally these are issues in moving data from the roaming network's authentication back to TMO to verify the device is a valid roaming device. Nothing you can do but keep trying. This plagues all networks at times even on non TMO accounts.
Yeah I realize now it had more to do with the devices than the SIMs. After all, even though they are marketed as Google Nexus devices, N5 and N7 are designed and built by two different companies, probably supporting slightly different networks. The thing is that I needed something that tethered, and when the tablet worked I didn't care
how it happened. Once I tested it and found it useless to me, I went and got a local SIM. Didn't really have time or the desire to investigate further.
I've been really happy overall with this whole free-roaming thing.
