New sim card does not work on old Nokia C7 and N86

Hi there, I was wondering if anyone else experienced this:

After upgrading sim card from old (large) o2 sim card to new nano-with-adapter, the new sim card works fine on both android and older, windows phones, but... if inserted into old symbian phones Nokia (C7 and N86), it makes these phones go into continuous loop of swithing on and off. The old (large) o2 sim card worked perfectly fine on these phones.

This does not happen with a virgin nano-with-adapter card, which works just fine on these Nokias.

Thank you

@a2a78 Yes, I've had similar issues when using adapters in these older phones with the spring loaded flap type of sim retention.

I think the problem could be down to alignment so try and see if you can position the sim slightly differently.

After struggling with adapters I ordered a completely new sim card from o2, used it in original (largest) size and after a sim swap the old nokia phones work again!

Thought that would be it.
