Q01: How can I confirm that my SIM card can support GTP-541M?
A01:
The frequency bands supported by the GTP-541M are: FDD LTE (Asia 4G system): B1/B3/B8 TDD LTE (China 4G system) : B38/B39/B40/B41 GSM/GPRS (2G system) 850/900/1800/1900 MHz WCDMA (3G system) 850/900/1900/2100 MHz
Please ask the SIM card carrier you want to use:
1.
Is there any support for the above bands?
2.
Whether the area where the GTP-541M is placed can receive the signal of this frequency band
Q02: Unable to register troubleshooting (4G light is abnormal)
A02:
Confirm that the antenna and SIM card are properly installed. ➢ Use your mobile phone to confirm if the SIM card can be registered. ➢ Confirm the SIM card by referring to step Q01. ➢ Confirm that the PIN Code is set correctly, or use your mobile phone to cancel the
PIN Code.
Turn on Utility to confirm if the signal strength is too low (< 30%) ModBusSMS function: Page.30 - Section 5.6 DIOSMS Features: Page.77 - Section 6.6 RMV function: Page.102 - Section 7.5
