We know that some users use our SIMs for roaming data in MIFI-devices (portable mobile routers). This is perfectly ok and the SIM´s are well suited for this.
In most MIFI devices you must choose which Authentication protocol you want (CHAP, PAP or None).
For Cobira SIMs this must be set to “None”
Contact us on support@cobira.co if you need further assistance.
