Gradwell Mobile allows you to use your mobile phone as a fully integrated Hosted PBX extension, simply by adding a SIM card to your handset.

You use a land line number on your mobile phone, so you can take calls to your office phone number on your mobile handset – and it is a proper mobile phone call, no fiddly VoIP is required.

You can also send and receive SMS messages from your mobile handset, using your landline number.

With all the features of a Hosted PBX and no long-term commitment, Gradwell Mobile delivers high speed, business grade telephony and mobile broadband. 

Personally, I will be trying out this. With no long term contract, what’s to lose?
