Hello, I have a GX450 Modem I recently purchased that supports Sprint.
Type MC7354
Network Operator SPRINT
Firmware Version SWI9X15C_05.05.63.01 r28860 CARMD-EV-FRMWR1 2015/07/02 11:04:50
SKU PRI ID and Version 9904566, 05.02
Carrier PRI ID and Version 9902350, SPRINT_005.037_000
I went to a T-Mobile store to purchase a SIM card and add this modem to my Sprint/T-Mobile account.
The guy at the store said T-Mobile won’t activate the device because its a CDMA device and doesnt support GSM
However, in the GX450 Hardware User Guide, it does show that the GX450 supports GSM/EDGE bands with the MC7354 radio
Can someone help me out here? Anyone have a GX450 currently connected to T-Mobile/LTE using an MC7354 radio?
My plan was to update the radio firmware to “Generic NA” , but, now im getting a storage full error, but, i guess thats a separate topic/question
I am working with T-Mobile to see if our current GX450 / Sprint will work. FYI, I have downloaded the 4.9.7 Firmware and have the 05.05.63.01 Radio for Sprint. There was not a new radio download for T-Mobile. I hope that that I can use the GSM network with this device.

Then I see the flashing RED and flashing RED+AMBER lights on the device accordingly.
I tried to upgrade the radio firmware to GENERIC but I’m getting “Device Full” errors.
Is there a way to free up space on the device via AT commands?
Ok, I did a little more digging (RTFM) and it looks like I can set the Carrier manually via +COPS
So, i went to the ACEmanager UI and made a few changes and now I can see the signal light is solid green but the network light is still flashing red+amber
My use case:
What I’m trying to do is use a low-cost MVNO (Tello) to leave a modem in my RV so I can monitor/control the thermostat remotely. I just need a simple data plan and Tello offers a 2GB plan for about $14/mos. So that’s what I’m trying to do. Tello is an MVNO on the T-Mobile network.
I feel like I’m getting closer and closer with ever test.
Ok, after some more testing and validating, I can confirm the modem is sending and receiving traffic. WiFi works and I can traverse the Internet successfully with a browser.
The modem network light is still flashing red+amber but I am able to send and receive packets successfully.
Going to resolve this as a successful test/implementation of Trello/T-Mobile on a GX450 using Sprint Radio Firmware.
My specs:
Sierra Wireless GX450
ALEOS v4.9.7
Radio Type MC7354
According to your description, when updating to Aleos 4.9.7 and the radio module firmware SWI9X15C_05.05.63.01, is the modem network light still flashing red+amber?
Please make sure you have properly attached the antennas to the device. Two antennas are required when connecting to an LTE network.
Correct. I have both antennas connected. It’s a pricey Poynting MIMO 5G pri/diversity antenna. After some more research, it looks like the LTE bands TELLO uses are not supported by the Sprint radio. It was only connecting at 2G.
I plugged in a different LTE modem (Digi Transport WR11) and now its using the full LTE bandwidth.
