iPad 3 is not connecting to 3G service internationally

Same problem here still on edge and not going on 3g. Same sim in my Iphone 4s now and work perfectly. I hoped the problem would be fixed. Damm apple

Hi, I upgraded yesterday and after it was connected only to 2G, I got frustrated because the problem persisted, but after a while, 15 minutes after it changed to 3G and has not failed since. Calvin, Mohit is a matter of patience, let the SIM inserted in the iPad and after a while it will connect, Greetings.

I left it for houres like this, moved the ipad from places to places so it changes the tower it connects to and no luck so far.

This really ****** me off...

After 3 months still not a uasable 3g connectio where the ipad2 and iphone 4s works flawless.

This sounds like an other problem when i do airplane mode on then off it searches waits for a while then edge

look what I did, go to Settings-operator (where one chooses the operator) - change it to MANUAL, usually is in automatic, and with it reconnects to my iPad 3G network, I hope this helps

I have an update. We have two carriers here in the Cayman Islands. LIME (Cable & Wireless) and DIGICEL. Both offer exactly the same network options and frequencies, including HSPA+ (2100MHZ). Up until the 5.1.1 update I could only get EDGE on my new iPad, regardless of which carrier SIM I used. Both SIMs are 3G enabled and tested in an iPad 2 and iPhone 4S. DIGICEL is my primary carrier and so yesterday, after applying the 5.1.1 update, I was hoping to see a 3G or H connection. Unfortunately there was no change. So I figured the update had done nothing. Just for kicks I tried my LIME SIM this morning and was surprised to see it connect via 3G (this SIM is not HSPA+ enabled because LIME have a separate plan for this). So now my LIME SIM gives me 3G in the new iPad but my DIGICEL one is stuck on EDGE. Considering the iPads are all carrier unlocked, and the two local carriers use exactly the same networks etc, I cannot understand why it will now work on one and not the other. I am going to get LIME to enable 4G(HSPA+) on my SIM to see if that works. I am pleased that it is working on one carrier but am now more confused and concerned that it doesn't work on both.

Lets us know. It can also be network problems, hlr, handovers reselection, switch, sim profile ect ect

I'm having same problem as catjbm.

The data SIM from the same of my iPhone carrier keeps staying on edge while the iPhone is solid 3G on same network (eMobile Ireland). I tried a Vodafone Ireland data SIM and it seems to work far more reliably. This is still the case following iOS 5.1.1 update.

I am in Costa Rica too

Claro is not working with 3G at all

Movistar and Kolbi work but you need to switch off the automatic carrier selection and select it manually.Then just a quick reset using the airplane mode and the new ipad ll get 3G servide (Only works with Movistar and Kolbi)

The 5.1.1 didnt solve the issue

The tip that gersoncr did could work. 2 of the 3 Costa Rican carriers work after switching off the automatic carrier selection

Works for me with kolbi carrier

Tried selecting network manual no go

I have had the same problem in Costa Rica and have been able to connect to the 3G in Kolbi and Movistar switching off Automatic Carrier selection and choosing it manually. I wonder if the iPad is expecting an LTE network and since it doesn't find one, it chooses the GSM network automatically and and skips 3G.

Even though the 5.1.1 update has allowed me to connect via 3G to one of our two local carriers LIME/Cable & Wireless) I do still need to do the manual carrier selection trick in order to get it to work. The other carrier (DIGICEL) won't connect with anything but EDGE. On paper the two carrier networks are identical, and even use the same communication/networking equipment so there must be something different with the DIGICEL deployment. DIGICEL are saying that Apple have to fix the problem, and I agreed with them when neither local carrier would work, but now that one is working I don't see how Apple can issue a separate fix for specific carriers.

The same problem with CLARO here in Costa Rica

Most likely, the sim card you have is either network-locked (there isn't Verizon or AT&T in some countries) or reigon-locked (only connects to US/NA 3G networks). You won't be able to connect to 3G in foreign countries UNLESS you have a sim card for that country. It also could be a hardware lock, where a US iPad will only connect to a US network, and British iPads will only connect to British networks (and so forth). I know this doesn't fix your problem, but it is a "proof of concept" type of thing.
