I have a Nokia phone for T-mobile in San Lucas. The capanies here use 1900 MHZ according to T-mobile which My phone works on it we called T-mobile berfore the trip to make sure and they said yes, but won't work. Any Ideas on how to make this work? Roaming is on and to thing says I can't access these cell phone services here.
You will have to contact T-mobile customer service to resolve the issue.
That would give you the opportunity to use a local SIM card. Any visit back to Mexico would also give you this cheaper calling rate if you didn't absolutely *need* to use your regular number. It's *possible* the GSM network you're trying to access is not accessible to T-Mo customers. But the CSRs will clear that up.

If the area you visited is remote maybe they have only one network that is incompatible with your phone. For example, I was surprised that my Nextel Blackberry worked in Guadalajara and surrounding cities in Mexico and also in Buenos Aires, Argentina, with some limits - the only operational features were data and direct connect (push-to-talk), while I couldn't make any phone calls myself, but could still receive calls from the US. Fortunately, they use direct connect feature a lot and often you will see an ad in the newspapers or a billboard with the corresponding PTT number.
We have phones on the Tigo network in Colombia. Tigo only has the 1900 band here.
They work fine! As a previous poster suggested, you should consider carrying an
unlocked phone and buying a prepaid SIM card from a local operator, in the area you are visiting. That will save you a *LOT* of $ on roaming charges. Generally,
in the Americas (North and South) the GSM operators use the 850 and/or 1900 GSM bands. With few, if any, exceptions, those are the GSM frequencies in use in the Americas. Your phone is a Nokia. They are possibly the best, for getting a signal
in weak signal areas.
