StaticElectricity 8 Report post Posted November 10, 2011 I recently bought a motorola photon 4G from hetal. A very fast phone with great features. I am using it on my airtel gsm card, and somehow I am just not able to get the USSD codes to work. I type *121# and call, the phone just says USSD code running, and after a while it would say MMI code cancelled. I was wondering if any of you have had a similar experience ? or is it a problem with all GSM Androids ? The phone is, btw, running android 2.3.4 Share this post Link to post Share on other sites

StaticElectricity 8 Report post Posted November 10, 2011 ^ Life is going to be very difficult on GSM without USSD codes. Does anyone know of a workaround? I asked about this issue to sadikk and he asked me to use a different dialer. Now I have no idea about what he meant by that. So I went ahead to the android maket and downloaded 2 apps called ussd dialers, but both of them did the exact same thing as was happening earlier. On a second note, I had the same problem on my blackberry 8830 , which was also a world phone (CDMA+GSM) . Seems so strange. Share this post Link to post Share on other sites

StaticElectricity 8 Report post Posted November 10, 2011 @rajan: Thanks for the link, but that app cannot be installed on the motorola photon. Also I tried other dialers (https://market.android.com/details?id=com.iba.ussdchecker&feature=related_apps) but same thing as I have mentioned in the above post. I remembered that while using the blackberry, I would dial 121 (customercare) and then as a conference call dial the USSD code. That would make it work on the blackberry. Tried it on the motorola photon but that also does not work. 1 Share this post Link to post Share on other sites
kshah 452 Report post Posted November 11, 2011 In bb world phone there was a turn around like making call to cc first them while in call dial ussd code. I read that android has ussd code running problem is it true? Or is it specific to world phones? Sent from my MB855 using Tapatalk 1 Share this post Link to post Share on other sites

mujeebrehman 78 Report post Posted November 12, 2011 Whoooaaa this phone seems to me as a trouble magnet the list of issues are endless. Even I had the same issue with USSD code for my secondary prepaid gsm sim. But I do not care much as 99.99% of time I am on my cdma billing number. However, if anyone can help me with conference calling over this phone I would really appreciate that. I need conference calling very badly for my office and personal use.This phone is a killer and I love it but most of its issues are killing me now. Share this post Link to post Share on other sites
rajanmehta 4,056 Report post Posted November 14, 2011 (edited) For USSD codes not working in Photon , try these solutions either singly or jointly. Can be tried in no particular order. One Put a comma after every # That is if you are dialling *121*5# Dial *121*5#, How to insert comma: Press options / settings button while dialing and select "add pause (,).. OR if your dialer can put comma through any other option Two Add + before the code That is if you are dialling *121# Dial *+121# Three Set the length of DTMF tones in call settings to Long instead of Normal. Four For some Samsung Phones, after disabling Mobile Tracker in Location and Security, USSD codes worked. Check if you have such a setting in Photon and disable it.

kshah 452 Report post Posted April 1, 2012 Motorola notoriously block NV items and controls radio behviour by NV rather than OS. Thats why in all moto global handsets, USSD codes do not work. Even when we load AOSP ROMs. Share this post Link to post Share on other sites
