S24 Ultra not compatible with carrier network

[userjF0D91YDFJ]

Is anyone else being told their S24 ultra is not compatible with their carrier network? We received our new phones yesterday and tried to activate them with our current carrier (Xfinity) and they are telling us our unlocked phones are showing up as not compatible.

Here is the list of supported US carriers. Ironically, the Select Your Service Provider screen is not displayed on the Galaxy S24 (this one's from an S23). As you can see in the 1st sceeenshot, Xfinity Mobile is indeed compatible. If your carrier is not displayed (such as Visible, Mint, Google Fi, or Spectrum Mobile), select Open (this is a wildcard option). If activating with a carrier outside of the US and Puerto Rico, choose Other Ways to Connect to a Mobile Network instead of Open.

If eSIMs are found, you will be asked if you want to add them. If none are found, the following options will appear (though the exact options depend on the carrier) (2nd screenshot).

ACTIVATE THROUGH SERVICE PROVIDER
Download your mobile plan through a carrier.

TRANSFER SIM FROM ANOTHER DEVICE
Use this option to transfer an eSIM from another device.
(Currently, in the Americas, only eSIM transfers from Galaxy devices are supported. Cross-platform and cross-OEM transfers will be available in One UI 6.1 and later.)

SCAN QR CODE (3rd SCREENSHOT)
Use this to scan a QR Code given by your carrier.
(The activation code entry method is no longer supported in the Americas.)

INSERT SIM CARD INTO THIS PHONE
If you have a physical SIM card, select this option.

SEARCH FOR ESIMS
Try searching for eSIMs again.

RECOVER DELETED ESIM
If you've accidentally deleted your eSIM, you can recover it here.

You can check with the device support page for your current carrier for the correct steps to add eSIMs.

When that screen comes up on the new phone it only showed T-Mobile. I called Samsung customer service to verify they did indeed send unlocked phones and they guarantee me they are.

Hmm, this is a problem. Does your model number end in U or U1? You can see it in Settings > About Phone.

U1

Mine ends in U1 and same issue here

[useruDnxSaoanv]

I have same issue and mine ends in a U. Can it be flashed or changed to. U1? Software or anything to do with my gift or is it a paper weight?

@useruDnxSaoanv "Can it be flashed or changed to. U1?"

You can't change the model number to end in U1.

If the device is carrier unlocked, you could flash the unlocked software on it but it would still end in U.

Tmobile new feature moved right over by itself. Didn't even have to call. It created new esim and registered the phone.

Most carriers cannot activate until Jan 31-Feb 1st. Samsung should have released the sims for the pre-orders. It’s Samsung ….not the carriers fault. Very disappointing!
