Um, what are you trying to tell me, Mint Mobile?

As Mint Mobile user, I received an email that says the following in the subject line:

Your 3G device will not be supported after 7/1

Umm, okay. Then in the email:

Your Apple iPhone 13 Pro Max has been identified as a 3G compatible device, but it is not compatible with 5G or 4G LTE bandwidths. Therefore, you will need to upgrade your phone to a 5G or 4G LTE compatible device before July 1, 2022.

Huh? You are really saying that iPhone 13 Pro Max are useless.

Who did your research?

iPhone 4S: The missing “Enable 3G” switch.

The “Enable 3G” switch is no longer present in iPhone 4S.  The purpose of disabling the 3G radio is to conserve battery life or forcing the iPhone to connect to EDGE network where 3G signals are weak.

iPhone 4S

The “Enable 3G” switch still present in iPhone 4 and iPhone 3GS running iOS 5.

iPhone 4 running iOS 5

UPDATE:
Threads about the missing “Enable 3GS” switch on Apple Support Communities.

Please let Apple know that you want this feature back, regardless if it was a bug or design decision.

Do I need to worry about AT&T new data plan? Apparently not.

I first was a bit worried about the new AT&T data plan, then after I checked my data usage I worried no more. I realized that most of the time I’d be in areas where I always have access to Wi-Fi network. I apparently used a lot less bandwidth on AT&T data network than I thought. Without any access to the Wi-Fi network, I’d easily gone over the newly introduced 2GB data cap in a week or less. I guess I’ll be paying AT&T less for my phone service.

For the past 6 months, my data usage never go over 1GB per month.

If I were to get an iPad 3G, I’d have no problem paying for the lesser data plan thanks to all those Wi-Fi Access Points.
