I know nothing about cell phones. I am graduating from a phone that has the slide out key board. Bought an AT&T LG Thrill 4G and found out it is out dated, extremely slow and the battery is crap. I need a pay as you go, to go with my Airvoice STANDARD sim card, that is new, 4G, preferably an 8 memory, good battery life and is kind to an old lady who is computer savvy, just not cellphone savvy. Please help.
A phone with 8GB of memory is a very up-to-date one. Here in England, we would pay top money to buy a phone with the specifications you want and to have it as a pay-as-you-go service. The discounted prices in shop windows are for contract phones or those limited to a monthly payment.
Give Samsung Galaxy 7s a miss until they sort the combustibilty problems and perhaps search your local e-Bay for an unlocked phone. Tighten the search to "unlocked 8GB Lollipop Marshmallow" for the latest two versions of Android operating systems and you might get lucky.
