Help No 3G on Desire S


Deleted User

Hey everyone.

I previously had a Nokia 6700 Classic that was also 3G enabled. This was on the Three network (a pay monthly contract). When at my uni room (in a quite isolated area) I could occasionally get a 3G signal. At home (in a major city) I nearly always got a 3G signal. (The icon in the corner changed a 3G icon)

After deciding to buy a new phone and not continuing with my contract, I brought a month old HTC Desire S from eBay which was locked to the o2 network.

On checking out prices and rates, I decided to unlock the phone so I can use my previous Three SIM card with the same number and taking out a 30 day SIM only contract that offers 1 GB of data allowance.

I activated the 'Mobile Network' option.

Whilst at my uni room I couldn't get a 3G signal, I thought this was due to the area and the phone having different capabilities than my previous phone.

However when I got home I still don't get a 3G signal either.

I put on my WiFi and this works great on all applications.
My brother (on Vodafone) has a little Wildfire and when he's connected to his 3G network, underneath the 'Mobile Network' tick box in the Settings menu, his says 'connected' whereas mine, whilst ticked, will say 'Connect to the Internet'.

The 'Network Mode' selected is set to 'GSM/WCDMA auto'.

Everything else on the phone works fine, texting, calling etc.

I'm guessing it's something to do with it not being an o2 SIM card. I have ordered a free o2 SIM to test this. I have also contacted HTC about this and they are yet to get back to me.

Just wondering if anyone else has had this problem, and/or knows how to fix this.

I would preferably like to stay with Three as the deal I have is perfect.

Thanks for reading, i'll keep you updated what happens, and any help would be greatly appreciated!

Sorry didn't know there was another section for the S. Thanks!

I have exactly the same problem:
I bought an old HTC Desire S, wifi connection is ok but impossible in 3g...

Did you find a solution?
I hope so...:thinking:

First thing to check is the APN (Access Point Name) settings.

Did you manually set-up the APN for the Three (or your provider's) network on your Desire S, or were the APN settings changed automatically once the SIM had registered on the network? There's a chance the Three APN may not be there or is wrong.

For APN settings (where the phone stores the settings for your provider's 3G connection), Menu > Settings > Wireless & networks > Mobile networks > Access Point Names > The 'Three' option should be selected > Select the Three option and make sure the settings are correct. You'll need to verify this with the settings on their website or with Three's customer services.

Then, Pull down Notification bar > Quick settings > Mobile network - On

Menu > Settings > Wireless & networks > Mobile network - On

Menu > Settings > Wireless & networks > Mobile networks > Enable always-on mobile data - On (if you want it on all the time and to test its connectivity)

If the Three APN settings are correct, then you should be getting a 3G connection.

If not, then get back and we can explore other possibilities.
