You need to check on the 3 website as they give you the time it takes to port a number. It depends on what time and which day of the week. As yesterday wa Sunday the porting may not be done until tomorrow. This is what 3 say:
Did you activate your Three SIM?
Your new Three SIM must be activated by 17:00 on the last working day before your transfer date.
If you’ve not activated it on time, don’t worry. Follow these steps and the transfer will be completed within 1 working day. Or 2 working days if done after 17:00, over the weekend, or on a Bank Holiday.
To activate your new Three SIM, put it into your device and switch it on.
When you see signal bars, that’s your SIM activated. You might need to switch Wi-Fi off to see the signal bars.
Once your SIM is active, you can use it immediately. Or you can go back to your old network SIM until the transfer is completed.
If you activated your SIM on time, but your number’s still not been transferred, please contact us.
