How to keep Philippines phone Sim active in UK?

In Philippines, phone sim gets deactivated if I don't add load for few months. If I bring Philippines Sim to UK, is there any way to keep it active for many years?

Register it as a roaming sim and make sure you load it regularly.

I recently sent load to a Philippine Globe sim using Ezetop

Fast and easy, doubtless there are many other ways to load remotely.

Is there any fixed timeline after which Sim gets decativated for Globe and Sun?

I'm not completely sure if it is 3-4 months.

I researched on Google, it's 120 days.
Apart from loading it regularly, is it also required to make a charging transaction, example sending a text or make a call?

Uhm, I don't think so. Only use mine to maintain online banking as Ph number is required.
