Three sim is not working in my Redmi Note 11T 5G mobile

Three sim is not working in my Redmi Note 11T 5G mobile, same is working in Samsung S25

Looks like Network bands supported by device are not compatible with Three network. Redmi Note 11T 5G mobile supports below bands. 

5G / 4G / 3G / 2G and 5G bands are : SA：n1/ n3/ n5/n8/ n28/ n40/ n78 NSA：n1/n3/n40/n784G: FDD-LTE Band B1, B3, B5, B8 TDD-LTE Band B40, B41WCDMA : B1/B2/B5/B82G: B2/B3/B5/B8

Please let me know if Three is having same network bands or frequency?

We didn't hear back from you on this, so I hoped to check in to see if you could share some extra info on the SIM and device issues you've been having.

Are you in a area/postcode with 5G? or only 4G?

Hello @sreeuk22,

Thanks for reaching out, and welcome to the Three Community.

Having checked this, it appears that Three should support at least some of these bands. Have you recently purchased the Redmi Note 11T device, and has the Three SIM not worked or displayed any service at all?

Do you see an indication on the device that suggests the network bands aren't compatible? 

Thanks,
Michael
