I need a decent Nokia phone on Orange PAYG which is, above everything else, LOUD enough to hear. My present phone 3210 has lost it's volume, how? I do not know but calls are so quiet thesedays. I've adjusted the settings to max and it makes no difference.

So what I need is a good basic phone. I don't care about ringtones, Java, WAP and all the other gubbins

Any suggestions?

If you are insisting on Nokia then try these phones which all cost less than £100 SIM-free.

Nokia 1100: small, grayscale, basic features (Calling, SMS), vibrating alerts, predictive text but no WAP etc.

Nokia 2100: about the same but a bit more stylish IMO. You can use XPress-on covers to customise it.
