The MiNE Media products recognise all common SIM cards from German mobile phone providers. However, we only use 02 and Telekom. With Vodafone, there are always problems with the bonding quality and the speed provided, among other things. That is why we strongly advise against using Vodafone cards.
Please note that the PIN code query must be deactivated for the SIM cards.
Please also note the APN settings for each network operator.
The products Q7, Q8, Q9 and R8 use a completely different bonding method than the M4 Mini. Here, too, there are no known limitations of SIM cards: Telekom, O2 and Vodafone work in any combination and quantity.
