*****UK **** HTTP Request over GPRS - What network to use ?

Hi

Trying to upload data from an arduino to a SQL database via GPRS and HTTP POST request.

GSM module is working fine for SMS & Phonecall but will not connect to mobile internet.

Currently using a PAYG vodafone SIM but worried this is where the issue is.....

Has anyone in the UK managed to perform an HTTP request via GPRS, if so what network did you use ?

Thanks

Martin

I have used Vodafone in the past, and O2, but currently use Asda mobile.

You are using the correct APN settings aren't you?
