But let's see:



Onesimcard with callback (Single SIM - only onesimcard): US to UK

US Incoming: FREE
UK Landline: €0.07 incoming callback + FREE landline UK = €0.07 (+ one time €0.01 data to trigger the callback if not on WIFI)
UK Mobile: €0.07 incoming callback + €0.005 mobile UK = €0.075 (+ one time €0.01 data to trigger the callback if not on WIFI)
SMS using SIM menu: $0.15
SMS using Fishtext with WebSMS on android: €0.03 (+ ~€0.03 data to send the SMS if not on WIFI)

Onesimcard with callback (dual-SIM - callback on 2nd local/regional SIM, showing +372 caller ID or any other caller ID): US to UK

US Incoming: FREE
UK Landline: FREE incoming callback + FREE landline UK = €0.00 (+ one time €0.01 data to trigger the callback if not on WIFI)
UK Mobile: FREE incoming callback + €0.005 mobile UK = €0.005 (+ one time €0.01 data to trigger the callback if not on WIFI)
SMS using SIM menu: $0.15
SMS using Fishtext with WebSMS on android: €0.03 (+ ~€0.03 data to send the SMS if not on WIFI)


In any case, for data the best is a 2nd local SIM with local data bundles in the dual-sim phone (but if only to trigger the callbacks the Onesimcard is good enough).



Canada to UK: same rates as US above.







Yes, Toggle Mobile already is my 2nd SIM in the dual-SIM phone for Europe.

so where do they advertise these rates, I have looked at Onesimcards website rates and i can only find the rates i published, as per there site, SIM Card - International cell phone rates
