Best practice international GSM setup

[MBK]

Keep in mind that I am talking about worldwide roaming (the subject of this thread), while you are talking about regional roaming.

But let's see:

Call cost back to UK from US using .
Tru $0.15 calling a landline $0.33 calling a mobile, SMS $0.15
Piranha $0.14 calling a landline $0.17 calling a mobile, SMS $0.15 Data $0.30 MB
OneSimcard $0.45 calling a landline $0.45 calling a mobile SMS $0.40 Data $1.00 MB

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 UK using SIM menu: $0.15
SMS UK using Fishtext with WebSMS app 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 UK using SIM menu: $0.15
SMS UK using Fishtext with WebSMS app 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).

Airbaltic card is €10 with 0 credit if this is an issue (€35 with 30 credit and €50 with 50 credit).

(€ 15 for "Airbaltic American Dream" SIM if you want free incoming in US & Mexico)

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