It’s really easy to make calls with your USA Unlimited SIM!
To make a call to a US number, simply dial 1 followed by the rest of the number.
For example, to call our Mobell office in the USA (2127855800), dial 1, then 2127855800, then the CALL key: 12127855800
To make an international call, simply dial 011, followed by the Country Code of the number you are trying to reach and then the rest of the number.
For example, to call Mobell in the UK (01543426999), dial 011, then 44 (the UK Country Code), then 1543426999 (without the leading zero), then the CALL key: 011441543426999
