MAX HD2 stuck at Obtaining IP address with Indian SIM Card


Hi, team, I m looking for the best solution for MAX HD2, I am using two Indian SIM cards 1. Airtel and 2.Vodafone
but I am facing a problem, the router not able to obtain IP Address on both of the connection …suggest me the solution…


SIM cards are not being authenticated by the mobile network.
Either they are:

  1. Not activated
  2. Need a custom APN / SIM PIN
  3. Locked to a previous device (like a smartphone) and can’t be used in the HD2.
  4. Are not local sims and need roaming turned on

Try the SIMs in another device (Dongle / smartphone) prove they work, then make sure the APN is right.


Thanks for replying Martin,
but I checked all the things that you mentioned ,
both SIM Cards are working properly in all other devices…
one thing i want to ask… product code of the devices is MAX-HD2-M-LTE-E-IP67,
is this Only for Europe,
if yes then this is the reason the Indian Sim Card not working in that…

Sim Cards which i used are prepaid…

pls make me understand solution in this situation.


Ok great, BUT remember in ‘normal’ devices (like phones, dongles) a mobile network operator can push custom AP settings automatically. it might be worth checking the APN settings for your mobile network and entering them manually in the HD2.

MAX-HD2-M-LTE-E-IP67 Supports 4G LTE:
B1, B3, B5, B7, B8, B20, B38 (TDD), B40(TDD), B41 (TDD)

There is a worldwide version (MAX-HD2-M-LTEA-W-IP67-G) that supports:
B1, B2, B3, B4, B5, B7, B8, B12, B13, B20, B25, B26, B29, B30, B41

What Bands does your mobile network use?


Thanks martin,
i will informed after trying manual APN.


Hey Martin,
I tried Custom APN now its get connected but network strength is very poor.

Can you suggest me the Antenna model which is compatible with MAX HD2 ?

we need both the antennas(Cellular Main and Diversity).



Any 50 Ohm antenna that covers the frequency bands used by your carrier would be compatible. There is a range of options - from slightly better than stock (such as the 5dBi omni-directional Proxicast antennas) to the vastly better directional MIMO antennas such as the xPol Poynting 698-700 antennas (that everybody seem to love - I have no personal experience with them) and what we use, MobileMark PND10-700/2700.
