Old Phone / New PAYG SIM

[Thomps557]

Hi, 

I've just ordered a brand new free PAYG sim from site which has come, no problems. 

I'm trying to now use it with a pretty old, non-smart Sony Ericcson phone. I'm getting full bars on the reception, but the message 'Insert Correct SIM card'

I've tried to register, in case I need to top-up to activate it, but it sends a text message verification, which I can't access...

Any ideas? Phone too old? Wrong type of SIM?

Thanks

Hello @Thomps557. 

Welcome to the EE Community.

Is the SIM you are using the correct size?

The phone you are using, is it open to the EE network?

Speak soon, 

Katie 🙂

Hi,

Yes, standard SIM - Old T-mobile phone.

I can see full bars on reception, but still saying 'Insert correct SIM
card'

Spoke to tech services, they said it was suspended, so unsp and added £1
credit - restarted... still the same...

Thanks for getting back to me @Thomps557. 

When did you speak with our technical care team?

Hi Katy,

About 30 mins ago, but line dropped. They text saying they would call but
back but nothing since.

Cheers,

Steve

Your phone needs unlocking from T-M to use an EE SIM.

Where did you yourself get this device itself originally? Did you buy it yourself new direct from EE/T-M or from a 3rd-party reseller or is it 2nd-hand? The unlocking process & costs are different. Was it originally on contract or PAYG?

I will look into it, thank you!
