Have I connected to 5G with RM520N-GL?

Hello all,

I have a RM520-GL in a GL.inet GL-M2 adapter. The unit is connected via USB.

I am located in the UK and am using the TalkMobile carrier. They are a virtual carrier using the Vodafone UK infrastructure.

The location I am in can receive 5G signal, I have tested this on an iPhone and on a Huawei H112-370 5G router with the same SIM card. The SIM is on a prepay unlimited data tariff with 5G data.

I am confused as to whether my Quectel unit has successfully connected to 5G network, or is just using LTE. I am getting around 200Mbps down and 40Mbps up, so it could be really good LTE, or slower 5G.

I believe the network I use does use 5G NSA, so I presume this means that I must also be partially using the LTE system to get 5G data.

When I check “servingcell” I see both LTE and 5G data, but when I check AT+QCSQ I only see LTE.

When +QNWPREFCFG: “mode_pref” is set to “AUTO” I get signal, when it is set to “NR5G” the connection never establishes.

Does using “NR5G” setting only work in standalone network and not NSA? Will I always see LTE even though I am actually getting 5G data because of NSA? Or does my Quectel have a problem registering with 5G network? Or perhaps my 5G signal is too weak?

Many thanks!

Here are some diagnostic data from the unit:

AcT value 13 is E-UTRAN-NR dual connectivity, so that should mean LTE signalling and 5G user data.

Dear @nickds
From the response, device had registered in NSA.
AT+QCSQ is not available with RM520N.
As you mentioned, it is virtual carrier, you can check with them about the speed.
You can also try the latest firmware, I will sent to your email.

Many thanks for your response, from reading into this status it does indeed confirm the 5G data.
