I have a Nexus 7 3G and I often need to send network service commands (e.g., to use top-up codes or to activate/de-activate data-plans), but can't find a way to do it from the tablet. Instead I'm forced to take the SIM card out of the Nexus and put it into a mobile phone temporarily. Is there a way to do this directly from the Nexus 7?

  • Could you please clarify a little how you do that in a phone then? This might give us (at least me) a clue what exactly you are missing/needing. Are you talking about USSD codes? In this case, you might try to install some dialer app from the playstore (just a raw guess). – Izzy Mar 02 '13 at 17:49
  • Sorry, I should have been more clear. Some carriers allow you to send 'service commands' to change some options in your subscription. With my current carrier, if I dial something like 139# on my cellphone, I can check my balance, while 100# allows me to perform other operations (incl. top-up). – nmc Mar 04 '13 at 02:15

I think USSD Checker is the app that you are looking for.

It allows you to send USSD codes to your network without the use of a dialer. I haven't tried it myself though so comment whether it works or not would help.

  • Thank you (can't vote up because of reputation). Strangely, none of these applications are compatible with my Nexus 7 3G... – nmc Mar 04 '13 at 06:28
  • It might be because the Telephony app is not installed by default. This is required to have SMS, Call functionality including sending USSD. You should try a custom ROM with telephony built-in and it should work. – forums Mar 04 '13 at 07:05
  • Thanks, but that is not very helpful - I'd rather avoid having to resort to custom ROMs to get what is usually standard functionality. – nmc Mar 04 '13 at 15:46
  • Any terminal commands available that will check USSD response? – NoBugs Sep 05 '13 at 03:37
