EUSTAR you are NOT informed as always..these +447 UK & permanent+1 US numbers are assigned directly from TRAVELSIM to their sim providers (airbalticcard, onesimcard etc). see here:
http://www.travelsim.com/toll-free-numbers/
ask airbalticcard again they gave you wrong information.
airbalticcard:
calls to their +447 number 0,15eur.per call
calls to their permanrnt +1 number 0,15eur.per minute
i have both +447 and +1 numbers attached to my airbalticcard for years and just rechecked now..for a 3:12 (192seconds) inbound call received through the +447 number i was charged 0.15eur. only.
+447 is free to be assigned, +1 costs 0,50eur.per month.
even with onesimcard (travelsim backbone too)
http://www.onesimcard.com/cell-phone-rates/#info Additional cost to receive call trough UK mobile number is charged per call, not per minute. : $0.25/per call connection fee
even with United World Telecom simcard (travelsim backbone too) calls to the UK number is charged per call , not per minute.
https://www.uwtmobile.com/products/g...im-cards/Basic . but 0,25$per call, so airbalticcard (0,15eur.per call) is cheaper in all cases.
Airbalticcard also within EU countries charge outgoing calls per second (30+1) ...UWT, Onesimcard and XXSIM not, they charge per minute (60+60)!
