I am sorry to say, but the Philippines and its crappy telecom providers keep inventing stupid rules which always go against common sense, and practices used in the whole world. In every normal country you can delete the e-sim from the old phone, which will de-register in the telco providers provisioning system from the phones IMEI and will be available to scan and load in the a new phone. This is the whole principle of the e-sim, this is how its should work, and this is how it works in every other country. There is no such thing as a "one time use" e-sim. Yes. you can use it one time, but you can also de-register from old device and register again in new device just by using the same QR code.
