Transfer to a cheaper equiv deal than I have now

There are cheaper deals for 35gb than mine right now online through a website with 1-4 months and then goes to the regular monthly.
Anyone ideas how I do this without having to keep cancelling and starting again ?

Unfortunately only for new customers you would need to port out and come back

Unfortunately you will have to do what is known as a triangle port, which involves basically transferring your number out to a different network, then transferring it back in on the new SIM card.
it is a royal pain but it will only take about 3 to 4 working days. If you start it on Monday

I suppose that would have to be done before the eSIM activates and the SIM card is shut off. Is that correct, or can it be done after the transition to the eSIM?
