Is Your HTC Sensation 4G Suffering Data Connectivity Issues? The Fix Is Easy.

Since the first few Sensation 4G’s were sold from Walmart a few days before June 15th a small number of Sensation 4G owners began to complain about data connectivity issues. Some users find themselves stuck on a 2G network having dropped off from 4G, some are suffering intermittent data issues with data working one minute and cut out the next. As it turns out there is a legitimate reason these phones have done this and the fixes are actually quite easy. T-Mobile’s own forums saw the issue start sometime around June 10th and thankfully in no time at all they’ve been able to pinpoint the problem.

So what are the fixes to those of you who might be suffering from data connectivity issues?

  1. The SIM card: If you are using a 2G SIM, perhaps the one you had before you purchased your Sensation 4G then this is a likely culprit and should be swapped out at your local T-Mobile store for a 3G/4G SIM. Your best best is just replace it with the SIM that came in the box.
  2. Ensuring that your data plan is properly provisioned with a 4G data plan. Customers who are on grandfathered plans, blackberry plans etc should make sure your Data SOC is on a 4G plan.
  3. If the above problems don’t work (and they should) the last resort is to do a little tinkering around by dialing: *#*#4636#*#* and then press “Phone Information” > Toggle Ciphering to OFF > Turn off Radio > Turn on Radio > Toggle Ciphoring to ON.

That’s it, the fixes are that simple and as you can see this problem isn’t really a phone problem at all. The Sensation 4G doesn’t appear to be suffering any sort of a horrendous software issue and the phone can be fixed within a matter of moments. Hope these fixes help you!

    Okay I have tried all 3 steps to the fix and guess what… it’s not fixed!  I have tried 3 different sim cards, first one that I had in my old Vibrant, then the one that came with the Sensation and a third I got from a TMO store.  (No luck)  I then tried step three (*#*#4636#*#*).  Did nothing.  I even tried setting the phone to WCDMA Only which is all fine in good if you are 100% positively always in a 4G area.  If you move one step out of 4G coverage your phone becomes a paper weight and you can’t even get voice calls.  Even when I have been in a 4G area showing with 4 bars my download speed is an average of 1 Mbps to 3 Mbps which is no where near the 14.4 speeds this phone should get and don’t even get me started on the no buffering…  My Vibrant was getting speeds of 5-6 Mbps so didn’t see why the data plan fix would help but being that I really want this phone to work I called Tmobile and had them change my grandfathered Unlimited Android plan to the (REQ 5 GB 4G Unl Data plan) Unlimited data – 5 GB of high-speed data included plan.  Made sure they also had my correct IMEI number registered and even had them re-register me on the network, instantly losing connection was resetting and then back on and yet… Still major data issues.  I am not a newbie to Android and feel I have done everything I can think of.  Last resort is to replace the phone with another one but really, what’s the chance the next one won’t have the same issues as this phone is not even 10 days old.  Other issues I’ve had is not being able to view my Picasa web albums.  I can see the thumbnail of the folder but when I click on the folder the one becomes a strobe light trying to load the picture but never does, even when connected to WiFi.  The HTC widget “Quick Record” doesn’t work and anyone notice that the “Car Panel” pre-cached maps that was a big deal was made about in promoting Sense 3.0 is missing.   I have also emailed HTC support and got a response a day later asking for more specifics which I responded back right away but have not heard anything back…  So anyone have any other ideas?  David, can your ninja’s get any official word if it’s software, hardware or just SEVERAL lemons that got shipped out.

      I don’t have the phone, but that sounds a lot like a baseband issue to me, in which case it’s a software issure. Sadly rooting the phone, or installing a custom rom whenever they come out won’t help much, although my G2X is better than it used to be after doing that. A new one might very well work, could have just been a bad batch of phones.

      I’ve tried it with two phones and still have the same issues. Tmobile refuses to admit there is an issue, but there is. I even put my sim in my Incredible S and it works perfectly.

    I have a few Glitches
    1.  App icons moved to sd go to the generic android icon after reboot.
    2.  Sometimes the screen cant sense that I’m trying to answer a call.
    3.  My wife’s phone had signal problems, but replacing the sim worked and had to make sure settings were set for android at tmobile.
    4.  Speakerphone is not loud enough.
    5.  It always asks for timezone after every reboot.
    This phone is a lot better than G1, and Blackberry 9700 (wife’s)

    The strange thing that I have noticed with my sensation 4g is that it does seem to randomly lose the data connection but if I just wait a few seconds without trying to use the data at all is comes back. I have only noticed this while tethering. All of the posts that I have looked at regarding these issues do not seem to be the same issue that I am having. Not really an issue but more of an annoyance.

    I just bought the phone two days ago, upgraded sim chips and plans. Flew to Germany and NO connection for data. flew to Italy today, no data. Tried all four local providers. Tried this fix and no help. Called tmobile and they said: we cannot guanrantee you can connect to any roaming data provider. So, not in Frankfurt? Not in Bologna? Not a good answer, but no options… I will have to go from wifi to wifi and that stinks.

  • Sensational

    I live in Canada and the only issue I had with this phone was a bad batch was sent to my province and we had issues with the phone constantly resetting itself. HTC said that they had an update coming out but it wasn’t targeting the issues we were having. Fortunately it did fix the problem though. I can’t say I have had any issues with the 4G. I am on Bell and only once had the data drop but have not had it happen since.

  • Dopehousex3

    Same here my sensation drops from 4g to G then gos to 2g then back to 4g a couple of times a day. And I work next to a tmobile store! I got a new seem up graded my data plan but nothing helps and tmobile CS act like they have no idea what I’m talking about.

    This phone SUCKS… I wished I could give it back. The radio is weak and makes the phone totaly useless… Can’t forgive myself for buying this crap for the full price.

    I read everything here and none of this worked. I have tried fixes from other forums and have read about people who have had replacement phones do the same exact thing and nothing was fixed. Eventually, I figured it out on my own and fixed it.

    Keep in mind this is a fix for those who have the issue where WiFi turns on and off every few seconds and the 4G goes to 2g then turns off altogether and then back on and repeats the cycle. This is does NOT have to do with any “death grip” issues.

    Power down and take off the back cover. Using a small plastic tool of some sort or a toothpick, raise the brass antenna connectors on the exposed back of the phone (the ones that come in contact with the metal/fabric material on the back casing). Make sure they are not lifted too high up or you could lose the alignment with the back casing altogether. Carefully reattach the back cover and reboot the phone.

    Problem solved.

    This is a very nice phone but the whole antenna in the back cover design was a poor engineering decision. My advice, once you get it working properly via this method, avoid having to remove the back too often. Unfortunately, you cannot see connection between the contacts. But rest assured, when they are touching correctly, you will have no issues.

    My phone works flawlessly now.
