Yes. Watch out for those data charges.

Telcel's Blackberry Unlimited DOES NOT cover any traffic other than BIS traffic. Here's the proof:

Almost $400 dollars in data usage for about 33 MB. This plan DOES include the Blackberry Unlimited addon for $240 MXN (Blackberry Int Ser C).

There is a supposedly unlimited data plan for $800 MXN with Telcel and about $600 MXN for 30 MB per month.

El plan de datos Blackberry de Telcel NO incluye uso ilimitado de otro tráfico que no sea Blackberry. Esto incluye POP3 y HTTP. Cuidado con esas cuentas.
