I looked up the T-Mobile frequency chart,
1900 MHz 2 4G LTE; 4G (HSPA+); 3G (UMTS/HSPA); 2G (GSM/GPRS/EDGE) 1700/2100 MHz (AWS) 4 4G LTE; 4G (HSPA+); 3G (UMTS/HSPA) 66 4G LTE 850 MHz 5 4G LTE 700 MHz 12 4G LTE 600 MHz 71 4G LTE
I'm evaluating a phone, the Huawei P20 Pro 128GB. This phone isn't sold by T-Mobile but it seems to mostly support the bands, however it's lacking support for Band 71.
- How much service-degradation can I expect from lacking a specific band?
- Is there any way to weigh the importance of those bands individually?
Making me even more curious, I'm currently using a Samsung S5 which was sold to me by T-Mobile, and it doesn't support 600 MHz -- maybe I'm missing out on a lot, maybe the 600 MHz band isn't actually used anywhere?
