Best Telephone chip contract at the moment

[MCLUMA]

Hi

Now I have found this forum with very helpful people I have the following question

I have a Videx GSM intercom system, and want to know what is currently the best contract / pay as you go chip available

I currently run a virgin pay as you go chip. But are there any better options / providers available, as most GSM intercoms call one or two number anyway

Thanks
