Upgrade of phone and allowance

[Robjam123]

I just upgraded to a new 5g compatable phone and new upgraded allowance .
I recieved my new phone, that included a new sim.
Do i use my old sim from my old 4g phone ?
Or do i use the new sim ?
If i use the old sim will it be 5g compatible ?
If i use the new sim, will it be a new number.
TIA

You need to use your new sim to get 5G

Your old sim will only be 4G compatible

You need to do a sim swap

Follow this guide

Guide: Sim Swap: a mini guide 2017 update 

Text SWAP from your OLD sim and follow the instructions in the return text

Currently the 5g sim is blank.

If you want to use it, start a sim swap from your old sim Guide: Sim Swap: a mini guide 2017 update 

If not, your new allowances will already be on your old sim, so just use it in the new phone.
