Well, this depends on which countries you will travel, for how long and how much data you are going to consume. Generally, Mexican providers have good options going north (to US, Canada), but not south (to Central America).

In Central America only some Movistar networks offer affordable roaming solutions for prepaid so far, Claro only for postpaid. Check the relevant country articles.

If you stay for longer and want to use much data, it's cheaper to buy a new SIM. If you stay for short, you might also check our international section and check how much your own provider is going to charge for roaming. Travelling multiple countries, it's always a decision between roaming surcharges and the extra effort to get a local SIM. To help you with your decision, you should know the local rates by checking the article of every country you are planning to travel.
