Does any know the set of AT commands that can re-program the Quectel modems. I have an RM500QAE and an EM16G. I have been trying to fix my internet and performed firmware upgrades and full factory resets on both modems but I am having issues with my speeds now. I would like to re-program for tmobile LTE. Pease help as I use these for my work. Thank you

I am getting 10 mb download speed and a crazy 55 mb upload after I factory reset and updated firmware on Quectel RM500QAE 5g modem. Before the reset I was getting over 100mb down and about 20 upload. Any ideas on a settings in the AT commands that would help with this issue of speed? Something has changed in the modem that is causing my throttled speeds.
Queried Command:
AT&V
&C: 1
&D: 2
&F: 0
&W: 0
E: 1
Q: 0
V: 1
X: 4
Z: 0
S0: 0
S3: 13
S4: 10
S5: 8
S6: 2
S7: 0
S8: 2
S10: 15
OK
