How to get my sim card back?

I sent my iPhone off for repairs with lloyds bank ( mobile phone insurance) i have it back now and its fix but they haven't returned my sim card. I really don't know what to do and I'm so angry with them.

You shouldn't have sent it - they have no use for it.

I forgot to take it

To be honest? Just get another. All four major carriers will give you a replacement SIM for an amazing price. Ready to hear it?

NOTHING!

ABSOLUTELY FREE!

But seriously, just call your carrier.
