60 second fix, not mandatory but for tinkerers it is lol... T-Mobile is rolling out the nations largest Standalone 5G Network. Some folks have reported only seeing 3xSA Bands instead of 4. This is only on X75 equipped devices. If you don’t feel comfortable doing this please reach out via live chat. Credit for this fix: Reddit: vrabie-mica
if you have 4 x 5G Bands DO NOT employ the fix
Make sure your APN is correct
Home Internet: fbb.home or fast.t-mobile.com
WARNING T-MOBILE HOME INTERNET ONLY
PHONE PLANS AND TABS SHOULD ALREADY SEE 4 BANDS IF NOT MESSAGE ME
