I have an old phone that still has the sim card in it. Does anyone know if this could be used with a pay as u go card?

If not, is it wise...or worthy to try for one off ebay?

If the pay as you go sim is on the same network as the old sim it should work!

I agree with Mark -

the shop where you buy a pre pay sim should be able to tell you if it is the same as the sim in your old phone (take it with you to the shop)...

I have a 3rd generation phone which has a 'u' sim - I cannot use a pre pay sim in my phone or it will kill my phone!!

Just ask at the shop where you buy pre paid

I think it will work. I had a prepaid account with T-mobile ( when they were voicestream) and a plan, when one of my batteries would die I could just switch the sim and use the other phone. I'm not sure if other providers have different technology for their prepaid accounts but I would highly doubt it.
