Hello everyone,
I’ve been working for years with HiloNcV2 and later with HL6528RD. According to my experience, HiloNcV2 modems are not as good as any standard phone regarding connectivity (even with a good external antenna!).
For instance, I often face the case where old phone (eg. Nokia 3210) is able to attach/register a network quickly and with a good signal while HiloNcV2 either never connect or after a longer time. Obviously with same SIM card and at the same location.
Unfortunately, with HL6528RD it is even worse! Here is my last case:
I have one HiloNcV2 and one HL6528 RD with the same kind of external antenna both at the same location and both with the same operator SIM card (french operator Free).
The HiloNcV2 is able to attach an authorised roaming network quite easily with a good signal :

On the contrary, the HL6528RD is able to attach this authorised roaming network only a few time and with a poorer signal. Most of the time it attaches a forbidden roaming network with an even worse signal (I can say that because the Hilo sometimes also attachs this forbidden roaming network that has a poorer signal):

I tried to change switch SIM card and external antennas and the behavior is always the same.
Both Hilo and HL are in automatic attach mode:
AT+COPS=0
I don’t know what I should do to make HL and Hilo register/attach better. Is it a good idea to try manual mode, given that my customers and I are not expert in GSM/GPRS network??
It is also worth mentioning that I experienced strange registration issue with Hilo already :
I also never had answer to my questions in those posts :
Is HL6528RD worse than Hilo? Should we switch to an other HL model?
Thanks in advance for your answers
