I bought an ex-Vodaphone Huawei G300, and was happy to find that it was unlocked - I put in my Giffgaff SIM, and immediately had phone and internet access.

However, I really want to use the phone on Three, but although calls and texts can be made and received, I can get no internet.

I tapped 'New APN', and set it up in accordance with 3, but even though I saved it after inputting their settings, the APN screen remained blank, and no connection could be obtained.

The settings entered were:

Name – 3 Internet

APN - three.co.uk

Proxy, Port, Username, Password & Server - blank

MMSC - http://mms.um.three.co.uk:10021/mmsc

MMS PROXY - mms.three.co.uk

MMS Port - 8799

MCC - 234

MNC - 15

Authentication type - None

APN type left blank

Is there something I don't know??
