Hello dear Umair, and welcome to Jawwy from stc. Glad to assist you.
There is no issue, I need you to check the following after checking the number if it existed in Cellular Plans or not if it's not then:
App > MoreManage Devices > Choose Your Number > eSIM QR-Code
If you are able to use it again, that's will be great if not I'm afraid that you need to order an eSIM SWAP, and to order it it's so easy and it comes immediately to you once you purchase it from HERE. ( Chose eSIM type and make sure to prepare the Absher account before, eSIM it's not applicable from branches).
With thanks and appreciation,
Ahmed Omar
