Hi,
First thank you all in advance for all the great knowledge found on this site.

I need to get a phone for my dad (he will be using very limited calls/texts and checking/sending email 2x a day otherwise the phone will be turned off) and I think I narrowed it down to the moto e4 and the $125/365 days airtime card.

A couple of questions:

1- Is it really that easy to unlock and activate the verizon moto e4 using the ebay code or should I not risk it and just buy an unlocked one from the outset?

2- Is there a place to apply the promo codes without having to give a credit card to the company?

3- If I run out of data I can just buy a data only card and add it at anytime?

Any other tips?

Thank you!
