Carrier Aggregation - Xiaomi Mi 10T / 10T Pro Questions & Answers

completely stock mi10t here and i live in US, how do i get carrier aggregation unlocked?

Mi 10T do not support Carrier Aggregation combinations used in US. You can check here supported Carrier Aggregation combinations: https://cacombos.com/device/M2007J3SY
There is no way to unlock combinations. It's not recommend buy device outside from region because then these devices may not support all features used on home network.

LTE bands combinations

Hi guys,
I know that HTC USA version has different LTE bands in comparison with European and Asian variants.
However what I want to know if the combination of bands to do carrier aggregation are different. For example, both devices support bands B7 and B28 but I don't know if both variations support using these bands together.
Google Pixel lists all the possible combinations of bands in order to get carrier aggregation but I can't find this information for HTC 10.
Do you know if American version support bands 7 and 28 together in order to get carrier aggregation?

I think it's best to ask oneplus support or ask your question open beta 13 thread on oneplus forums.

US Radio/Modem to enbale US 5G bands on G988N/G9880?

I want to get an asian variant of the s20 ultra so I can unlock my bootloader but those varients don't support the bands for T-Mobile 5G. Would it be possible to somehow enable the T-Mobile US bands on that variant?
600 MHz is low band and i think this device antenna or other RF-elements doesn't support such low band. 5G is too new also and you have to also somehow define en-dc combinations so i don't recommend buy this variant. If you like make sure 5G works, buy device from home market.

Unlock additional DR (5G) bands?

Hi all,
I'm wondering whether it is possible in some way to unlock additional NR bands on the S20. As far as I understand the Snapdragon 865 chipset, it comes as a fully-fledged 5G mobile platform which can be used in all countries and which supports all possible NR frequencies/bands.
So, it seems to me, that Samsung just locks off the majority of bands in the different models (for example, I got the G9810 and like to use it overall in Europe. However, Samsung only delivers the bands N1 and N78 but not e.g. N28).
Would be great if anybody could give me a hint about this.

I think there is no way to add more bands because these are defined to hardware. But i'm very interested about your model 4G Carrier Aggregation Combinations. These can get from log file: https://mt-tech.fi/en/how-to-get-4g...ons-from-your-android-phone/#Qualcomm_devices . Could you please share to me this BandInfo file? You can send this to https://cacombos.com/contribute
check out the Samsung Band Selection app on the Play Store. Supposedly, it can unlock hidden bands.
I looked at it but I'm unsure which bands are available to Sprint/ T Mobile in the St. Louis area. I set to Automatic. Playing it safe I guess .
Also when I switch to 5G it doen't show any bands. The S20 + is capable of more 5G bands I hear

Only can disable/enable bands what hardware support. If it doesn't you can't just randomly unlock bands.
