New V2 router, use old SIM?

[monkeyboy72]

Hi, I am an existing customer using NR5103E router, after calling 3 on Friday I today received the new V2 version but there was no SIM included so I took the sim out of the old router and placed in the new one hours ago but internet light is still red 

Was I supposed to receive a new sim also and my old SIM won't work in this new router?,

My fault, i had a sim lock on, put sim back into old router removed sim lock placed sim back into new router working straight away

Hey @monkeyboy72,

Glad to hear you figured this out! Thanks for taking the time to update the community, hopefully that helps other users in the future.

I can confirm that we don't generally replace SIM cards when upgrading or replacing devices. It's only necessary if there's a different size of SIM required.

Thanks,
Jonathan
