Freematics ONE+H GPS Not Working and data cell not stable

[hitomebored]

First of all, the forum wont allow me to post on Freematics Hardware, as it kept logged me out whenever i wanted to post.

I have purchased Freematics ONE+H and load it with telelogger.ino via IDE.
1. I tried to use GNSS_STANDALONE, however when i check the buffer buf, this is the following string:

$GNIFO,000000,00000000,0,0,0,0,0,0,9999*C7
�P'�?�0�? @?�����*?�0�? ��
�p'�?���?

2. I tried to use GNSS_CELLULAR and check the buffer after sending atcommands to SIM7070, and it returns the following result when i check the m_buffer received:

+CGNSINF: 0,,,,,,,,,,,,,,,,,

Please help why all the gps module are not working properly.

Note that i have supplied the module to 12V with my variable power supply.
