[RTuesday]

I've also just got back from Mexico.

Last wednesday, the 092 "balance" command started working, and it confirmed that incoming calls in Mexico are free (however, the account is debited 2 or 4c each time the balance is checked, which looks like a bug).

Still can't make outgoing calls, nor send or receive sms. But, using a second phone I could trigger callbacks, so using callbackworld or (more reliably) gphone I could call the UK and US for around 15c/min, which for Mexico is an excellent rate. (with the local sims, it mostly costs more than that to make local calls, or to receive calls from outside the local area).

So for my extremely limited case it was a success (far cheaper than any other solution for making international calls from a gsm phone in Mexico).

Note: the 092 balance enquiry isn't working now I'm back the US, I don't know if that's because it doesn't work here yet or if it has stopped working again in the last few days.

I saw some comments on here about the length of the number: it's a perfectly normal 12 digits as those digits include the country code. Exactly the same length as most UK numbers.
