Like I posted last summer T-Mobile went to a combined service area of US/Mexico/Canada last year and this in turn has forced the other mainline US carriers to roll out similar offers. Since then I have have used it often in Cozumel and various cities in central Mexico. T-Mobile and most carriers use local cell towers, primarily Telcel, and voice is normally good but data throughput varies and this is also true with other cell and cable networks. Often, due to traffic, the networks slow to a crawl during peak periods, they simply lack the bandwith verses the load placed on the network infrastructure. During off peak times the bandwith is adequate to very good.
The other thing to consider is that unlike a duel Sim solution if your carrier allows you to call Mexico that is only for out going calls from your phone. Local calls to your USA number are international from Mexican number's. Most dive shops have a work around such as a US VOIP like Magic Jack (which often fails during peak internet periods) but not necessarily other business and individuals.
