Sim card worked before I lost it and works in another mobile phone.
I am wondering if you have tried another sim card in your newly found phone?
In theory there should be no problems just put your sim back in and make calls.
I am wondering If Tesco have changed service provider in the last 6 months? If they have it could explain your problem.
Asda mobile changed provider about a year ago from Vodafone to EE and my phone stopped working because it wasn't an unlocked phone. As it turned out I had to replace my phone for one that was unlocked because it wasn't worth the expense and trouble of having the old one unlocked. The old one still works fine on Vodafone and O2.
Just a thought. Another thought is perhaps it developed a fault while it was lost or maybe someone has been fiddling with it in that time.
There are lots of aftermarket phone shops around with specialists to give advice. The Tesco helpline might be able to help.
Good luck!

You must unlock your phone using samsung sgh-m150 unlock code for tesco network. This code can you get from tesco or you can buy from third party sites, but don't try to use free samsung unlock code from internet since most of them is a fake code and it will not work on your phone.
