Using an unlocked GSM cell phone, a callback service, and a cheap SIM card, I make international calls from my cell phone from about 8 cents a minute while traveling abroad.
AT&T gave me the unlock code for my cell phone just for asking. There are plenty of SIM cards issued by European providers that offer free incoming calls throughout much of the world. And using a callback service, you convert outgoing calls into incoming calls. When I call the U.S. from Spain with my cell phone, I pay about 8 cents a minute.
Or at least I used to. My SIM card of choice was 09 Mobile from Iceland. But they became defunct. And I hadn’t been happy with the other SIM services out there. Yesterday I was offered the recommendation on Flyertalk for eKit Passport SIM (not their ‘global premium SIM’). It has free incoming calls in over 60 countries, and a ton of additional countries at between 9 and 49 cents a minute. That’ll work. It’s $20 plus $3 shipping, and comes with $10 talk credit.
Using that SIM in conjunction with a service like Call Back World, I’m set.
It works as follows:
- Dial Callback World. Let it ring once. Hang up.
- Callback World calls me, I answer, and dial the number I’m trying to reach.
- I have an incoming call (from Callbackworld), no charge from the cell service/sim provider.
- I pay only the long distance charges billed by Callback World, which are reasonable from most countries.
