Opinions on Best SIM card

CelTrek (which gives you a U.S. number) charges (for Costa Rica)19 cents incoming, 29 cents out to U.S. They also cover all Euro countries at varying rates - roughly the same price as other intl. cards if you factor in the cost to call the premium overseas numbers.
I believe I read here, recently, that one of those other intl. carriers now does cover CR, but can't find the post. If i recall, their rates were only about 10-15 cents more than CelTrek. Other intl. cards don't cover CR.
I assume you know CR does not have prepaid on their own system.

P.S. As DRN said, there is no "best" SIM.

Just found that United Mobile (+423) added CR. Incoming 25 cents (plus cost to call +423 cell) and $1.09 to call U.S.

You may want to consider getting 2 international callback sims. Most have long expiration dates which can be extended by making a brief call or sending an sms text message a couple of times a year, and many can be easily refilled over the web. The United Mobile brand has been around for many years and use Mobilekom Liechtenstein as the backbone carrier. CelTrek I think uses Orange-Israel as the backbone carrier and is a newer operation, but has better rates in some countries (and worse in others) and lets you choose an incoming number in the US, UK or France.

That way if
1) there's a technical glitch with one card that can't be solved by redialing or selection of local carrier,
2) one callback sim offers a better rate than the other in the country your in, or
3) one sim lets you roam on a carrier with a stronger signal where you are trying to make a call from,

you can just swap sim cards.

I use an LG G6, wife an S7) A/o Oct 20, 2013 no need for intl prepaid as T-Mobile U.S. includes voice roaming at 20¢/min (in and out)., unlimited text (in and out), and unlimited data in 140+ countries. My Plan -[6 lines] U.S. T-Mobile unlimited minutes (incoming and outgoing), unlimited text, fast data on each line. that $145/mo. total! . (In U.S. no surcharge for calling a cell.) If a line exceeds 2G of data in a month, pay $10 more for that line. [That only happens a couple times/year. Last edited by snidely; 18-05-2007 at 01:21..
