iPhone 5G SIM card requirements

I am an existing AT&T Wireless customers with an iPhone 11 Pro and I have an iPhone 12 Pro on order directly from Apple. The iPhone 12 was purchased full price, unlocked, with no SIM.

I have seen that the iPhone 11 Pro SIM with not work in an iPhone 12 because of 5G. Is this correct?

Can I put the SIM from my iPhone 11 Pro in the iPhone 12 Pro? If so, will it work, but just not enable 5G?

If I need a new AT&T 5G enabled SIM card for my iPhone 12 Pro what are my options for obtaining one with my current iPhone 11Pro phone number? I assume I can go to a local AT&T retail store, but can I order the appropriate iPhone 12 SIM online and have it delivered to my house with my current iPhone 11 Pro phone number?

Greetings @vjcinajr,

 

We understand you'd like to know if you can take the SIM card from your iPhone 11 Pro and inserted into the iPhone 12 Pro and still be able to get 5G.

 

To answer that question, it will be in your best interest to order a new SIM card so, you may be able to get all the functions and features. You can order a new SIM card at your local retail store or you can purchase online.

I got a SIM card from my local. AT&T retail store for my iPhone 12 Pro and they programmed the SIM card with my phone number and inserted it in my new phone. Worked perfectly. No charge.

@vjcinajr, you CLEARLY did NOT answer the question.  

Will 5G functions work without activating a new SIM card, yes or no?  

Currently my active sim card from my 6s is in my 12 Pro.  The cellular voice and data work perfectly but there is NO 5G functionality nor are there 5G options in the settings menu under  Cellular Data.

Yes or no?

From what I understand from the AT&T store employee, 5G service requires a new SIM card in an iPhone 12. I told the AT&T rep, at the store, that I did not intend to change my service plan to include 5G (my current plan is an old plan that is no longer offered and does not include 5G service). In the future, if I want 5G I will have to change plans, which will cost me about an additional $30 / mo..They said that I should get a new SIM card anyway, no charge. 

If you are asking what would have happened if I just used my old iPhone 11 SIM, would it just work for voice and 4G/LTE or not I'm not 100% sure but I think it might have been OK. In that case, I would not have had the option to get a 5G service because the old SIM does not support it.

I also have no idea how the iPhone 12 eSIM works regarding 5G. I suspect it should support 5G but I am not sure. I also don't know if it is possible to use the eSIM with no physical SIM installed.

On this topic:

I upgraded from an iPhone 11 Pro Max to an iPhone 12 Pro Max and my primary AT&T line is actually using eSim.

Must I obtain a new '5G compatible AT&T SIM CARD' to get true 5G speeds, or will the iPhone 12 Pro Max be smart enough to let my eSim settings enjoy the fast speeds??

Know this!  These criminals won’t let ANY old or grandfathered plan use 5G.

YUP!!!

For me I go from 70 plus tax to 105 plus tax with a Signature discount just to get 5G, and be able to hotspot. 

Back to the old days of eye popping excruciatingly expensive service.  

We did a verizon upgrade without any additional cost!!!!

I had the equal problem and the re-verification labored at first then two weeks later the identical difficulty turned into there once more. For the following few weeks every week we did the verification and it would paintings for a pair days then kick us off once more here. After that few weeks now it doesn't do anything and we have not had get entry to again. Hopefully it works out nicely for you
