When using my PAYG vodaphone mobile phone lately, just to check it is still working (as I rarely use it). Sometimes it connects, but most times it beeps and does nothing. Checking for the balance (about £10), or for the number, brings "rejected" on the screen. Any ideas? p.s it is pretty old, perhaps 8 years.
Thanks for the suggestions everyone. I tried cleaning the sim card contacts and reseating, but it made no difference. The battery only holds a charge for 4-5 days (its age), even when the phone is off. So I think I will get a new phone, a quick look round shows you can pick one up for £5 - £10, plus £10 calls. Many thanks for your help. :)
