Can you use same sim card as previous ok case?
No, Iām a representative of a cellular company, and the modem is located in another city, at the clientās place. I had the first modem, fixed the problem and gave it to them, now they wanted to launch the second modem themselves, with your instructions, which they did to you a week ago, but they canāt fix the problem on the second modem. the first SIM card was ours, now they use their own SIM card
then it is hard to identify which is the factor causing the problem
You might need to ship your sim card to them
how can I open all the bands where I tested 2600 MHz was, and where they are located 1800/2100 LTE is. maybe because of this?
which band number are you talking about?
when I tested the first modem, I tested 2600 MHz and the client has a base station that runs 1800/2100LTE. maybe because of this, you canāt catch a mobile network? how can I make all bands activate?
for your first modem, it was tested on LTE B7:
What is the current testing band with the base station now?
Is it LTE B1 and LTE B3?
Below is the band supported by EM7411:
base station working B1/B3, by default will working B3.
then these bands are not supported by EM7411 module
thabk you feedback.
our client asks which modem can be purchased to make bands B1/B3/B7/B28 work?
how about this?
