If you are using SIM card other than Monimoto's default - you will need to enter APN address that you should be able to get from the GSM operator that the SIM card belongs to. However, if you are trying to use a pre-paid SIM card and it is empty - you will most likely not be able to pair Monimoto with your phone until you put money into you SIM card.

If you are using Monimoto SIM card and got asked for the APN settings - enter m2m.tele2.com 

Password is not required.  This mentioned APN is default parameter that comes from factory.

Note: Paired device remembers APN untill you unpair it from your phone or restore default parameters.

Even if you restore, the default APN parameter is m2m.tele2.com
