You don't "need it" B20 is for 4G, and operators use plenty of other 4G frecuency bands. You have 5G and 3G as well, unless your operator exclusively uses B20 (which would be definitely weird). I've had Xhinese Xiaomis for the past 4 years and never missed that band at all. In Spain, only Yoigo uses it for instance.But I need LTE Band 20, so it doesn't work...

Mobile networks and carriers in Germany use 2 GSM bands, 1 UMTS band, and 3 LTE bands. Find out if your unlocked phone or mobile device will work in Germany
