Could Not Activate Cellular Data Network: You Are Not Subscribed to a Cellular Data Service
If you recently updated your iPhone firmware, or jailbroke/unlocked your iPhone to use it with a different carrier, you may have encountered the following error: Could Not Activate Cellular Data Network: You Are Not Subscribed to a Cellular Data Service
This error often appears after jailbreaking and/or unlocking and it is mostly characterized by the fact that your iPhone can’t connect to the internet using the cellular data network, and you can’t send text messages anymore.
The first thing to do in that case is to reset the network settings and reboot your iPhone. If it still doesn’t work, then there is a more radical fix that will put everything back on track.
First, get on wifi and visit this website http://www.unlockit.co.nz/#_Custom from your iPhone. You should see this page, which will allow you to create a custom APN.
Under “Carrier”, tap the drop down menu and choose your carrier. Note that there are many carriers listed there and that it might take you a bit of scrolling down to get you where you want. So choose the right carrier and tap “Done”. This should populate the custom APN info.
Once the custom APN fields are populated, tap “Create Profile” and wait a bit. It will exit Safari, and take you to the settings application. Finally, just tap “Install” and this will set up your custom APN on your iPhone. Reboot your iPhone and you should now have Edge and 3G connectivity.

I didt that but with the webpage you told us. The one that lets you enable tethering as well.
Anyway, now I have problems with wi-fi… I’ve got this blank untouchable option in settings telling me “no wi-fi”. Do you happen to know sth about it?
I had this problem the other day but didn’t want to do this website thing so I connected to itunes and preformed a sync, turned phone off and on and was able to access the data network again without any problems. hope this helps.
will this break your voicemail?
Thanks! This worked great! Saved me loads of time

Thank you so much for this. I was worried my unlocked iPhone would be pretty useless, but this fixed the no data plan issue in a heart beat.
i recently restored my iphone and it upgraded to 3.1 now i get that message and can’t access the internet any tips?
I tried this and however now when i try to access the internet via 3g, the message doesn’t appear, although it has the “loading symbol” and never loads anything. This goes for Facebook and other apps that use the internet. Any help would be great please.

I have an at&t Blackberry with a data paln. When I put the sim in my iPhone, I get the “You are not subscribed to a cellular data plan”. Will this fix this? I am not unlocked by the way.
Will this lock my phone? I have an unlocked 3gs on 3.1.2 with T-Mobile. Sorry, I’m a little paranoid lol I just want a clear answer saying that it won’t lock it up.
this is a god send!! Thanks so much! I was without data for 1 month and didn’t know what to do. I am even paying ATT $$ for data plan and they can’t seem to help! THanks !
I have no data plan, and I did this, I get the EDGE and 3G connectivity, Will I be charged for this? I did everything it said, Custom APN. Thanks!

Im on tmobile and I had 3 people try to do this easy fix and they couldnt, they all unlocked my 2g and wifi worked but not internet with out wifi….THANK YOU!!!
What manofsteel1982 wrote also worked for me too.
My iPhone 3G 16GB was locked to Rogers in Canada … I jailbroke and unlocked using Blackra1n for use on the Bell network. Right when switching the SIM I had the “Could Not Activate Cellular Data Network” error.
All I did was connect to iTunes, which then prompted a new cellular update, updated and synced and it works fine now.
Just Jailbroke and Unlocked my iphone 3g myself (first time I ever had an iPhone) using blackra1n (google it). There’s a bunch of tutorials on youtube on exactly how to do it but its so easy I did it on my own instead of paying those people on craigslist that charge $30.
I recieved this error and than I followed the steps and my 3g internet worked (I’m on T-mobile and note that on the drop down menu there are 2 t-mobile options; I chose the first). I could go on a bunch of sites and the prob seemed fix.
Only thing is that my phone wont connect to youtube for some reason…
any know why?
thanx this worked great!!!
the best 2g phone back in action after update to 3.1
Thanks it works!
