iPad 3 Why 3G does not work after being on WiFi

My serial: DLXHC8

I think getting this into the press will move things along. I'll pass this onto my buddies at skynews and the guardian. Lets see how quickly Apple moves then - they hate bad press.

I have the same problem in Turkey. I got new Turkcell SIM replacing my AT&T card yesturday. I was working untill I switch to WiFi and I cannot go back to my Turkcell one. I have been tried to reset and reboot-nothing is work.

I have the same type of problem with my iPad3. I'm in Missouri, using AT&T. There is some spotty 4G coverage in the area to which the iPad will connect without difficulty. But as I travel in the area, it shows no connectivity. My iPhone can easily connect to 3G, but the iPad doesn't seem to even see the 3G or connect until it's either on Edge network or 4G again.

Any suggestions?

I'm in Canada on the Rogers network, what has actually worked for me latetly (past couple days) is this:

I've turned off LTE under cellular data, and since then I have not had a problem.

The thing with Rogers in my city is that the LTE coverage is in the core of the city, in the suburbs not so much, and everywhere I've had the problem has been in a 3g coverage area only, yet my LTE switch was turned on.

Now that I've turned off LTE, these same areas (3g coverage only) that I was having problems with before, I am on the 3g network without the issue.

I turned off automatic carrier and set Optus manually. 3G seems to be working for the last couple hours.

Ok, so it's been a few hours now and 3G is still good after setting carrier settings to manual. Touch wood it continues. It's The longest it's ever worked.

Mine is a Singapore 64GB 4G and my serial is DLXH

telcom is Singtel

and this 3G problem is pretty bad for me as it affects me at work.

Same here in Germany. Vodafone already replaced my SIM with no improvement. Serial is DLXH8..

Go to settings -> Carrier, and turn off automatic carrier. It will search for the telecom providers near you, yours will pop up, then select it. I've done it this morning and it's been good until now.

Just tried it - while on the phone with apple support in parallel - and it didn't help me. Apple support told me that they are aware of this and they're working on a fix. Will propably be a software update.

Thank you for your help anyway.

I googled "ipad dlxh" and the results start with 3g proplems from all around the globe. On macuser.de, a german apple forum, this thread has already 128 pages containing over 1.300 posts. Time to fix this.

Mine is DLXH85

same problem.. Czech republic, O2 3G 16GB, DLXHC9

It is a cause for complaint? or iOS error and next update to fix it ? THX

DLXH8 here in UK. Same problem. Had the dreaded iPhone 3GS call drop out problem a couple of years back. Am I mad or am I mental for buying another Apple product?

Hi guys, this morning I went to the apple store located in Milano where I bought it and they change it, then since this morning the problem seems to be disappeared ..... I'll let you know. In the next days I'll travel a lot and I can verify if this fix or not.

If yes the only real answer is "hardware problem"
