What I suggest if you have the opportunity to go anywhere south of the USA is buying a 2$ claro SIM chip and putting 2$ on it at least once every 3 months or so in order to maintain it (Can even maintain payments over the internet as long as you can understand the Spanish website). This makes the monthly cost around 66 cents a month/$7.92 a year for an SMS verification mule, and it will receive texts anywhere that has GSM band 1 without having to activate roaming or anything expensive like that.
