S22 Ultra network issues

[useren6zn9p5jz]

Hey y'all,

I'm hoping someone here can help me resolve this issue. I recently switched to an unlocked S22 ultra bought from the Samsung experience store out where I'm at. Due to the 3g sunset & my previous phone model not being compatible with the new network I upgraded. Unfortunately ever since, I have had the same issue I had with my previous phone, a note 8, on the s22 ultra. That is, I'm unable to make or receive phone calls even the this phone is supposed to be compatible with the new network I can however, like before, send/receive text messages & access mobile data. 

My question here is if anyone has experienced this problem & if so, how did you got about resolving it?

I'm presently going through my cell provider AT&T to see if it's an issue on their end. As of yet no luck, they're still looking into it.

Any help would be appreciated.

When you upgraded your phone did you request a new Sim card? It may be possible that you have an older Sim card that doesn't support 5g, also try Installing Google carrier services which updates your phone's cellular information

Also, make sure that your phone IMEI number is registered on your carrier

Not sure the answer to your question but I can say where I'm located in Pennsylvania with my unlocked s22 ultra my reception leaves a TON to be desired.... Definitely making me second guess going the unlocked route. At this point I'm thinking I should have sacrificed memory for better reception in order to fully utilize T-Mobiles towers. Bc now I'm losing reception in places I never ever lost it on my note 20 ultra from TMO.

Make sure that you update Google carrier services on your phone, Pennsylvania is a tuff place to get cellular service, also make sure that you have a newer sim card to support the Sprint, T mobile tower conversions, not sure how memory is affected your calling abilities

I have an S22 Ultra & I'm also on the T-mobile network. Though this test was early in the morning, I got abt 3x the speed on what my internet provider give which is 200 down/10mbps up. Typically I get 300-450mbps on my data network.

I have the s22 ultra with no problems. I would go into at&t and get a new Sim witch was already said. I just put my Sim in and everything works

Not sure if it will be any help....I have an S22 Ultra here, but I don't have a SIM card in it yet. There is no "Mobile Networks" or "Network Mode" in any setting anywhere. So, I opened "Connections" in the Settings, and typed "mobile network" in the search data field. Several options showed up that looked like it would be possible to use 4G LTE instead of 5G, but as I have no SIM card in, they are all grey / inactive. I would be curious to know if you are able to change the network setting to 4G LTE in any of those setting options, and if so, if it stays at the setting you put it at and doesn't switch back to 5G on its own. I would like to be able to turn off 5G so my phone won't be always searching for it and drain the battery. Maybe if you are able to change your phone to 4G LTE you might also solve the trouble you're having.

Did you get your answer on how to turn off 5G? I can help if not.
