Is anybody else still having problems internationally?

We're in Lima, Peru and we had problems yesterday, the 17th. Data was very slow and I couldn't make a phone call to local or US numbers, other than T-Mobile 611. (I can make calls on wifi though.)

The rep said she'd call back to Mrs. Fredd's phone but that call failed.

My phone is slow to connect to internet as well. I don't know if it's a problem with my phone or something else.

On Jan. 1 Mrs. Fredd couldn't make or receive calls in Canada, although data worked fine, and my phone worked, so we've had more problems recently than we've ever had since switching to T-Mobile.
