Freematics connecting to incompatible network on roaming card
Posted: Wed Feb 21, 2024 2:19 am
Hey everyone,
I recently received my first ever Freematics One+ with the SIM7070G module.
I purchased a SIM card from simbase.
Simbase supports multiple operators in my country, Germany, like O2, E-Plus and Vodafone.
Nine times out of ten, I'm being connected to the Vodafone network, however according to simbase, only O2 supports LTE-M in my country.
Therefore, any attempt to transmit data over the Vodafone network results in a timeout.
I only have a very limited understanding of programming, and an even more limited understanding of how this SIM7070G works.
I tried limiting the bands as well as manually configuring O2 as the prefered operator in the library, however with no success.
I have already ordered SIM cards from other providers in the area to test out, but ultimately, I'd love for this one to work due to the great price/performance ratio of their service.
