Comparison of International Multi-Country SIM Cards
I am comparing some international multi-country SIM cards for a bunch of countries of interest to me
Criteria for inclusion
1. U.S. number included (no Isle of Man or Estonia incoming numbers!)
2. No monthly fee
3. No expiration
4. Free incoming SMS
The two cards I have so far are Truphone and Knowroaming.
Truphone is a very good deal in "Truphone Zone" countries (US, UK, Australia, Hong Kong, Netherlands, Germany, Poland and Spain) but rates are high to outrageous in most other countries.
Knowroaming is costlier than Truphone in the the "Truphone Zone" countries, but is usually much less expensive in other countries, with a few extreme examples.
Knowroaming does not charge for data when using Whatsapp, which can save greatly on messaging and voice calls over Whatsapp (high-latency on calls).
Are there other multi-country SIM cards that meet those four criteria that anyone knows of?
I have both of these cards. Truphone was used a lot earlier this year in Germany, Hungary, Austria, and the U.S. and it worked well, but the next trips are to countries where Truphone is very expensive. I just got some Knowroaming SIM cards and so far it's not so great because SMS is not working.
