roaming sim + unlimited calls

GadgetKen · 28-11-2010, 02:12

An interesting idea for people who make a high volume of international phone calls and travel to many countries...but don't think anything like this currently exists (if someone knows differently please chime in).

Problem is to have unlimited international calls in multiple countries a provider would have to charge a very high base fee per month.

A VOIP device (e.g. Skype) would come close for computer to computer phone calls, or very low rate calls to many countries from a VOIP device to a landline, but this scheme would be dependent on free or low cost high speed internet being widely available...unfortunately it is not like that everywhere.

A more realistic way to accomplish this would be to have a dual, triple or quad sim phone with unlimited usage sim chips dedicated to commonly visited countries. For instance the US has several resellers that have "unlimited" (but not unreasonable) service that includes international long distance to certain countries. The AT&T MVNO I use called Jolt, has a US$50/month plan that includes unlimited calls and international long distance: JoltMobile.com But I just use their $.15/minute flat rate plan that includes international long distance because my calling needs are not that great. Of course, the sim chip would be useless outside the USA for roaming (other than emergency calls) so this is not a one sim chip solution.

GadgetKen -
Their site is hopeless as far as info is concerned. I can't find their intl. calling rates. At one place they say free calling to 70 countries - with an asterisk next to that line. No explanation.
Anyway, this isn't a roaming SIM and with all other U.S. carriers you can make use of Google Voice (GV) to place calls cheaply to intl destinations. To most lst world landlines - 2 cents/min. With GV and a smart fone, the calling is seamless.

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.
