Depends on the server you want to reach. Same country you can get latency ~20 ms. If you get lucky also lower. But haven't seen anything below 10 ms. Also "-92

Depends on the server you want to reach. Same country you can get latency ~20 ms. If you get lucky also lower. But haven't seen anything below 10 ms. Also "-92 dBm" doesn't say much. There are 4 relevant values for LTE: Rssi (probably your -92, the most irrelevant one), Rsrp, Rsrq and Sinr.
