    6, 6S or 7. I just retired a 6S for a 7. Company provided. Both are excellent phones.

    Yeah but as time goes on AT&T will continue to cut bandwidth from HSPA/UMTS. The experience will just get worse. I certainly would not recommend a 3G only phone this late in the game. 6S or 6S Plus would be a safe bet for a few years.

    Can you compare a 6s and 6s plus ?
    So far that seems like the best choice ,

    And they are not new enough for the status symbol Apple owners to want anymore !

    6s Plus has a larger, higher resolution screen, better battery life, and optical image stabilization on the rear camera... otherwise they are the same phone pretty much.

    Costs less than $10 if you buy the battery yourself and install it yourself. Installing is easy as long as you pay attention to details.

    One good thing about AT&T is that they are fairly conservative about aligning their spectrum & technologies to continue to support older devices. Yes, they did drop 2G but AFAIK they've kept 3G running on either 850 or 1900 MHz just about everywhere. So, in theory an old iPhone 3Gs would still work. T-Mobile OTOH, may shift 3G up to the AWS band, drop it altogether or never deploy it in the first place, so many older 3G devices won't work with them. One is in-effect forced to update his phone even when his old phone is working well enough.

    Anyway, I agree with the majority here and advise an iPhone 6 or newer but with the qualification that even older phones will still work. There are many Android phones that give good service too.

    I wouldn’t necessarily say they’re conservative about keeping spectrum on legacy technologies. AT&T has 160 MHz of spectrum on LTE where I live, and 10 MHz on UMTS.

    T-Mobile has better support for older devices. They still have 2G GSM/EDGE up, along with 3G. At&t shut down their GSM network.

    One more difference: The iPhone 6s is more durable than the 6s Plus.

    In my experience, the 6s+ also gets better reception. My 6s+ certainly does better than my wife's 6s anyway.

    6s+ with a Qualcomm chipset is what you want. Make sure to get the At&t version as that has band 30 also.

    All 6s models have the Qualcomm modem. It was the 7/7+/8/8+/X that used the Qualcomm only on some models. Though it is possible that some older phones used different modems.
    iPhone X is my current primary phone. I have older model iPhones and Moto phones available on other lines. Currently prepaid, though would consider postpaid on right plan.

    The first iPhones used Infineon modems, which was bought by Intel.

    iPhone 6s would be better as for me. I take into account performance, iOS versions supported, compatibility with apps and your carrier.

    I think as others have said, the 6S and SE would be my pick (6 in a pinch). Most Best Buys and some Walmarts still carry AT&T Prepaid SEs for $200, which you can put an existing postpaid SIM in instead. As far as compatibility/longevity, the SE has the A9 processor, which is still considered quite powerful and should have software support for quite awhile (the 2017 iPad, iPhone 6S/6S Plus, and original iPad Pros all used chips in that family...A9/A9X). Despite the smaller screen, I'd argue it's the same or better in many ways when compared with the 6.
