How do I use my CallBlue GSM without changing my existing mobile number?
• Give friends, family, and colleagues your new number to use whilst you are abroad, AND/OR • Leave a voicemail on your existing mobile phone number giving callers your World SIM number to contact you on, AND/OR • Simply forward your calls from your existing mobile to your CallBlue low cost travel SIM number (please note that call diversion does normally attract a small service charge from your existing service provider. You should check this with them. However it should still work out cheaper than receiving a call on your normal mobile number while abroad).
