It is the cheapest device from OnePlus with 5G connectivity. In addition, it is perfectly optimized for all the frequencies used by Spanish operators. Also, an advantage is that it includes several frequency bands.
5G: n1 (2100), n3 (1800), n7 (2600), n41 (2500), n78 (3500) 4G: B1 (2100), B2 (1900), B3 (1800), B4 (1700/2100 AWS 1 ), B5 (850), B7 (2600), B8 (900), B12 (700), B17 (700), B20 (800), B28 (700), B38 (TDD 2600), B39 (TDD 1900), B40 (TDD 2300), B41 (TDD 2500), B66 (1700/2100) 3G: B1 (2100), B2 (1900), B4 (1700/2100 AWS AF), B5 (850), B8 (900) 2G: CDMA BC0 (800), B2 (1900), B3 (1800), B5 (850), B8 (900)
To know the compatibility with other countries, you can consult the Kimovil Frequency Checker tool which will indicate if the frequencies are supported by your operators.
The WiFi works without problems. It has the IEEE 802.11a / b / g / n protocols for 2.4GHz networks, and the IEEE 802.11n protocol for 5GHz networks. Unfortunately does not include WiFi 6 (802.11ax).
As always, after subjecting it to a power test 10 meters from the router, the result has been good. I have also been able to perform a speed test with the 5G, obtaining quite good results and without any problem.
As for the GPS, the operation is fast and accurate. Have Dual band GPS L1 + L5, Galileo E1 + E5a, GLONASS G1 and Beidou for full connectivity.
It also has a dual Dual SIM slot for two nano SIM cards, compatible with VoLTE calls (which are done using the 4G connection). In this case, you can substitute a nano-SIM card for a micro-SD card to expand the internal memory.
As usual, it has USB OTG to add USB sticks and has Bluetooth 5.1 LE low comsumption. Also something that has surprised me is that it includes NFC to make payments in shops.
Does not have FM radio.
