Can someone tell me how can I connect my raspberry pi running android things using mobile sim/3g/4g data with internet? I want to use my android things in remote areas where there are no Wi-Fi. I want to know about the hardware details as well. Which modem to use and connect with raspberry pi in order to use internet connectivity from mobile sim.

  • That answer doesn't explain much, can you provide a better link?? – himanshu1496 Mar 09 '18 at 10:39
  • It depends what you module want to use: you need shield like [this](https://www.cooking-hacks.com/3g-gprs-shield-for-arduino-3g-gps) and use shield module AT-command set to establish and manage 3G connection and data transfer. Different modules use different AT-command sets. – Andrii Omelchenko Mar 09 '18 at 10:47
  • This is indeed a duplicate, both in the sense that the question is the same, and in that the answer there explains that there is no elegant solution *and* proposes a workaround. The sub question of which device to buy is a "shopping question" which is off topic through most of the Stack Exchange system with the possible exception of Hardware Recommendations SE. – Chris Stratton Mar 10 '18 at 20:35

You will need to buy 3G/4G modules. There are many vendors such as Telit, Ublox or Sierra Wireless.

    The framework does not have support for Internet connectivity through a cell network module right now. – Nick Felker Mar 09 '18 at 06:43
  • I am thinking of doing it via AT commands, ditching the framework? – Tay Wee Wen Mar 09 '18 at 06:47
  • @TayWeeWen while talking directly to the module from a unique app could be a possibility, the current text of your answer simply saying to buy a module is just a restatement of the most obvious part of the question, and neither helpful nor in any practical sense an answer. – Chris Stratton Mar 10 '18 at 20:33
