Why doesn't my Samsung Galaxy Tab S7+ work with a SIM card?
I've went to T-Mobile to get my SIM card for my tablet, and it doesn't seem to work with the sim card! Is it the sim card or the product itself?
Is this a good question?

Hi @humanoidcorn457,
Was the tablet purchased from a mobile phone service provider other than T-Mobile?
If so it may be network locked to that provider and needs to be unlocked for it to work with T-Mobile
Does it detect that the SIM card is inserted?
What information, if any, is shown in Settings > Connections > mobile Networks?
Has the SIM card lock been enabled? Go to Settings > Biometrics and security > Other security settings > Set up SIM card lock
Can you try another known working, same network, nano SIM card?
