I think Google Fi is a no brainer
I used to juggle sim cards when I traveled. I tried T-Mobile and Sprint internationally and hated the slow speeds and awful customer service.
If you spend any significant amount of time outside the US, and are from the US, I think Google Fi is a no-brainer for mobile phone service. It's cheap, reliable and has excellent customer service. It leverages both the Sprint and T-Mobile international networks seamlessly connecting to the strongest. When I was in Peru and T-Mobile's network was down it auto-connected to Sprint. When I was in New Zealand which had no Sprint partner it worked great with T-Mobile. I get LTE speed over 95% of the time. When connected to Wifi calls home are free. Otherwise 20 cents a minute. Free SMS worldwide. Pay for the mobile data you use. My monthly bills average less than $30 a month. Only downside is that it works best with the phones they sell, though it is now compatible with other phones (see their site). I'm a Pixel fan boy, think they are better than iPhones and now they have the mid-range priced 3 a series. I have used it in 14 countries (including Colombia).
If you are interested in learning more here is a like to the Google Fi site which has all the info. You also get $20 off if you sign up through this site.

[QUOTE=Chicafan;2359674]Here in the US Sprint's network might not be as ubiquitous as Verizon and AT&T but their international roaming is excellent. Two years ago Verizon's international plan was so expensive that I had to get a SIM card every time I traveled and it was not transparent- people could tell I was traveling if I called back to US. It was basically $40 for 100 mb data (which is nothing) and perhaps 100 minute talk time and the price of exceeding that was punitive. Sprint's international data roaming is free, although slower than 3G, but the option of buying some megabytes of 4G are available and a hell of a lot cheaper than Verizon's $40 for 100 mb. I just don't need it for wpp and FB in the streets of MDE or where wifi is available. Calls within Colombia or to US are 20 cents a minute.
