  Making calls

Making calls using YES ONE Sim is quite easy.

1. Key in the destination number you wish to call. Use the following dialing format:

           Example: For calling a Miami number dial +1305xxxxxxx#.
           Note: Do not use international prefix such as 00 or 011.

2. After dialing the destination number your phone will disconnect. Ignore any messages the phone may display during this process (even error messages).

3. After a slight pause you will receive a callback call from the YES ONE Sim switch. Answer the call normally.

4. Wait a moment to be connected to the destination number.

Receiving calls

Your friends and family can reach you by dialing either your UK phone number or your alias phone number.

Note: There is an additional charge of US$0.03 /minute for incoming calls to the your Alias number (your local country) or other alias phone number assigned to the YES ONE Sim card.

Please note the following important information. When calling to your UK number your friends or family will incur long distance or international call charges, but you will not be charged in countries where you have free incoming calls. Vice versa, when your family calls your alias phone number they will not be paying as this call would be a local call, but you will be charged a per minute rate. For current rate table please consult the YES Rates Section.
