When installing the sim card, seeing a small defect in the fixing of one of the 2 internal antennas, the plastic is broken because of too much tightening during assembly in the factory. Reported to SVB who replied that in the event of a malfunction, they would intervene. Always TOP after-sales service with SVB!
It seems that you can use any sim card but that's probably not true, after contacting glomex and the sim card provider (vikings), still no solution. Does not work with a wifi port that asks to confirm access. After having installed well, fixed almost definitively, everything worked for a short time and then, eternally disconnected. Sad to say but unreliable, zero glomex service, difficult return following installation.. In short, a lot of money wasted!
