If you are not planning on upgrading the phones soon, you might want to re-read my post on eSIMS on non-eSIM phones and see if the esim.me card would work for them. Take note of how you can use the card on an incompatible phone if you have a compatible phone to program the card with. There is the cost of the card,. but it’s cheaper than a new phone.
If you decide that this would work, I can help with the setup.
Irritating, the quote of your post failed.
