You've ordered a new dataplan and this will have a new phone number.

However, you have used the new SIM to replace your existing plan - which would leave the new dataplan unactivated (and now you don't have to SIM to activate against it)

You'll have to wait until the replacement has activated and use the new SIM in your phone - but it will be your existing dataplan and number.

You cannot (easily) keep your number with the new dataplan.
