N900 All telephony functions, including emergency calls, are disabled due to communication error. To recover, you might have to reboot the device

For the last two months I have been contemplating what to do with my N900 that started showing the error below:-

All telephony functions, including emergency calls, are disabled due to communication error. To recover, you might have to reboot the device.

When looking for a fix, placing a piece of paper above the simcard was my first option, but it didn’t work.

After giving up the one the phone, I was ready to try the risky approach of adding pressure to the GSM module as explained . Follow the instructions in the previous link and also make use of N900 Disassembly instructions.

To add pressure to the GSM modules, I also made of springs found in pens. Cut a total of four rings from the spring. Dip them in glue and place them on top of the modules as shown here.

My N900 is back to working again. Many thanks to ForeverYoung


Unlocking a Huawei 3G Modem, use it on multiple networks

Being able to use a locked Huawei 3G modem on another network involves two steps.

  1. Unlock the modem using Simbwa Phillip steps.
  2. Set the APN of the SIM Network whenever initializing the modem

Simbwa Phillip has some steps which I was able to follow to perfectly unlock my Huawei 3G modem.
I will just paste here the steps again so that you don’t have to bounce back and forth.

UTL Uganda Telecom KwikTok Makes Internet More affordable

April 19, 2011 59 comments
UTL has an amazing product called KwikTok where you key in a ussd *250# and you get 100mb data, 20 free SMS and 10 minutes of talk. I have been a disgruntled UTL customer since 2003 but nothing has never made me proud of being a UTL customer like KwikTok.

So why am I happy about KwikTok? Well the 100MB of data isn’t a joke. 100MB!!!! for only 250 shillings. If you calculate that for 31 days, that is if you spend 100MB per day that totals to 7750 Shillings. That means you buying 3.1GB for just 7,750 Shillings. Hmmmm Yeaaaaaa. Now that’s sweet. 100MB is enough for you to stay online the whole day and make a couple of skype audio calls. If your to compare it with the major player Orange that am subscribed to for 3G internet 3GB would cost you 85,000 Shillings.

You should be just too crazy to underlook the UTL free internet. This means if your like me and have an old product like Orange 3G internet. You move UTL to higher priority and use Orange Internet when UTL connection is off or extremely slow. That makes you reserve your orange data when you extremely need blazing speed. Not that the UTL internet connection is slow. You can do pretty alot with the UTL connection. Pages load pretty fast and if your crazy like me who is running a proxy on all my machines and my N900 phone then that means better performance. Skype calls using my phone-n900 and laptop are both clear.

Every good thing has some annoying bit. KwikTok data doesn’t go without a negative spot. One thing that pisses me off is when your connected through the phone or your working from the phone and the 100MB is exceeded you don’t get any warning and it automatically switches to using the normal profile of your airtime which is maddly expensive. Coz my phone squashes 4000 in just less than 10minutes when active. You should be aware of this.

Setting up crazy caching for orange 3G modem on FreeBSD

This is a guide to illustrate how to set up a 3G USB modem on FreeBSD. Due to the cap limit on the 3G plans on the market, there is need to maximize link usage hence the guide illustrates how to setup squid + squidGuard + bind caching server. On capped links you need to monitor usage of the link, so darkstat will come in handy.

In this setup I used an old ASUS board PC with Celeron processor 500 MHz, 256MB RAM + 150GB disk I had stashed away; it is the perfect piece for the Job. To be able to access internet all around the house, I purchased a cheap TP Link wireless ADSL 2+ modem router, it goes for around UGX 100,000, that’s around EUR 37. Read more…

Uganda Telecommunication Industry MTN, UTL, Zain, Warid ,Orange, Smile

December 21, 2009 1 comment

Uganda’s telecommunication sector has seen linear growth from one to six (December 2009) mobile operators.  Due to stiff competition for clientele, subscribers are enjoying good local and international call rates. The number of Value Added Service applications has shot up.

This year (2009) the SEACOM cable landed in Uganda, this has led to the shift in pricing schemes for internet connectivity. Internet has become cheaper for example an MTN link that was worth 1000+ dollars, now you can get it at 600 dollars and with better speeds. Read more…
