"Invalid SIM" on New Doro GSM Phone (Pay and Go)

[colinmel]

Title says it all really! Brand new unlocked Doro 1360 big button GSM only phone. Put in a new Pay and Go SIM and all I get is "Invalid SIM" when I turn it on. Really stuck now.

Sounds like you have a locked device, it is either region locked or network locked I would speak to Doro

@colinmel 

Where did you buy the phone from?

[colinmel]

Phone bought from Amazon UK. Brand new unlocked UK & Ireland model. Should be fine!

@colinmel 

Agreed, it should be fine.

It could be a faulty sim or it could be inserted incorrectly.

I would also check with Amazon and at least report your issue, just in case it turns out that the phone is faulty.

Edited to add that having checked on Amazon I notice it is 2g only and O2 sims are known to be hit and miss with 2g only devices.

I would order another free sim to try https://www.o2.co.uk/shop/sim-cards/pay-as-you-go

Thanks MI5, yes I have tried two O2 SIMs both with the same result. I think this will be going back to Amazon.

I also noticed issues with EE on the Amazon reviews @colinmel 

2g only phones aren't good on modern networks these days so I'd look for something capable of 3g at the very least.
