Hi,

 

First post here.

I would like to explain my problem with 3g in short.

 

Ipad 2 att version umts freq 850 900 1900 2100

Ipad 3 att vesrion umts freq 850 900 1900 2100

 

I'm outside the usa now. The local carrier has 3g hpsa+/umts is using freq 850.

 

The sim card with proper apn setting in the ipad 2 i have 3g without a problem. When i put the same simcard in the in the ipad 3 i dont get 3g at all i only get edge. Both ipad in general about show carrier 12.0.

 

Called apple support they couldn't help me at all please see your local carrier.

I know bought ipad have the same freq for umts i know i have the correct apn setting.

 

No clue why it wouldn't work with 3g on the new ipad. I hope somebody can help me.

 

Thanks in advance

    This is a known issue, albeit one that Apple hasn't officially confirmed. I am an Apple reseller in the Cayman Islands and personally own an iPad 2 and iPad 3. The local carriers support HSPA+ 2100MHz. On my iPad 2 I connected to the locall carriers 3G network, due to the lack of HSPA+ support. With the iPad 3 I was looking forward to connecting via '4G' HSPA+. Both local carriers have confirmed that their networks are compatible with the new iPad 3, and they also pointed out that several 'other manufacturers tablets' are working fine on their 4G networks via HSPA+. However, when I transferred my SIM from the iPad 2 to the iPad 3 I could only connect via EDGE. I tried resetting the iPad, restoring the iPad, swapping SIM cards etc. Nothing works. On these forums I have seen similar postings from users in Japan, Singapore and elsewhere. So it is a software rather than a hardware issue and one that Apple will hopefully resolve in iOS 5.1.1 or earlier via a modem firmware or carrier update.

    Probblem:3G not connecting at all with local carrier card

     

    Networks in Suriname:

    Frequency:UMTS 850mhz band

    GSM 900mhz Band

    GSM 900 mhz Band, 1800 mhz Band
900mhz Uplink 890.20 mhz – 902.40 mhz

      Downlink935.20 mhz – 947.40 mhz

    1800mhz

     

    Specifications ipad radio frequency:

    iPad 2:GSM/EDGE 8500/900/1800/1900 mhz

    UMTS/HSPA 850/900/1900/2100 mhz

     

    iPad 3: GSM/EDGE 8500/900/1800/1900 mhz

    UMTS/HSPA 850/900/1900/2100 mhz

    LTE 700/2100 mhz

     

    After each test:

    -Reset network settings

    -Reset Setting

    -Reset and clear contents

    -Restore through iTunes

    always setup ipad as new ipad, no backup restore

    Also tried forcing on network, removing ipad from carrier automatic

    Tried different new sim card Uniqa network and telesur network

     

     

    Test performed:

     

    Ipad 3rd gen:

    Uniqa sim card, Network UNIQA: Results EDGE only no 3g

    Uniqa staff(CTO) put a trace on the phone number(ipad 3 never tries to connect to 3g network. It doesn’t fail it just never connects, it connect straight to EDGE/GSM network. Apn entered correctly.

    SIM ICCID reading in General -> About

    Cellular Data Number “unknown” in General -> About

     

    2) Telesur sim card: Result “No service”

    When you turn automatic carrier select off, you do see all 3 networks. When selecting telesur GSM you will still have no service

    SIM ICCID reading in General -> About

    Cellular Data Number “unknown” in General -> About

    Restoring iPad from iTunes 4 times in a row.. Telesur network now works.

     

    3)ATT sim card(activated in the USA) added international roaming plan

    After 1 minute it connects/roams on UNIQA with 3g, you can browse use everything.

    SIM ICCID reading in General -> About

    Cellular Data Number “+1786….” in General -> About

    If I have 3g connection with ATT roaming sim on Uniqa 3g network I get disconnected from 3G by doing any of these steps and 3g will never come back up:

    Switch cellular data on/off

    Airplane mode on/off

    Ipad to sleep

    Turn off ipad

    However to get 3G back just connect ipad to power(usb cable + orginal charger) now you get 3g instantly back can do data on/off, airplane mode on/off, ipad to sleep, turn of ipad and you will get 3G back. If power not connected only a erase content and reset will get you 3G back

     

    4) Digicel sim card: ipad goes on digicel edge network, with correct apn browsing works

    SIM ICCID reading in General -> About

    Cellular Data Number “+1786….” in General -> About

     

     

    Ipad 2nd gen:

     

    Uniqa sim card, Network UNIQA: Results network connection on 3g

    Browsing and everything works.

    Trace on the phone # in the switch of Uniqa, ipad 2 connects to 3g

     

    SIM ICCID reading in General -> About

    Cellular Data Number “unknown” in General -> About

     

    Telesur sim cardNon 3g:Edge network browsing works

    3G usim:3G working and browsing works

    SIM ICCID reading in General -> About

    Cellular Data Number “unknown” in General -> About

     

    ATT sim card with roaming: Result: roams on Uniqa 3g network within 5 seconds

    SIM ICCID reading in General -> About

    Cellular Data Number “+1786….” in General -> About

     

    4) Digicel sim card: ipad goes on digicel edge network, with correct apn browsing works

    SIM ICCID reading in General -> About

    Cellular Data Number “+1786….” in General -> About

    Questions:

    How can att sim roam on Uniqa 3g and uniqa’s sim doesn’t connect on 3G but EDGE only

    How can telesur sim card work(edge and 3g) in ipad 2 and show no service in ipad3?(after flashing 4 times, working on edge, couldn’t test 3g)

    Both iPad 2 and iPad 3 have identical frequencies for GSM and UMTS but still I get “no service” or “edge only” on ipad 3

     

    Other networks/Countries problems too:

    Problems with new Ipad 3 on edge only and ipad 2, ipad 1, iphone, 4 iphone 4S confirmed cases in Cayman Islands, Suriname, Costa Rica, Japan, Indonesia.

     

     

     

    Calls to Apple Support:

    First call:

    Restore network setting

    Reset all settings

    Result no 3g on Uniqa

     

    2nd call:

    Explain att working

    Restore ipad through iTunes

    Results: no 3g on Uniqa

    3rd call:

    Apple assistant said the problem could be:

    -Hardware problem

    -Software bug

    -Network incompatible with ipad 3(why does it work with ipad2)

    -Sim card not good(tried that no luck)

    Apple would like to diagnose the ipad, I agreed to send ipad in for testing with this report and sim cards

     

     

    This is my testing and report that will go to apple with ipad and sim cards

    Fyi received a verizon model today no luck at all no 3g on uniqa, telesur sim working in both awaiting my telesur 3g sim card

    Im having the exact same problem in Costa Rica, i contacted 2 of the carriers and they told me that they have already report the problem to apple, and the expect a solution for iOS 5.1.2

     

    Apple Support couldnt help. So until they solve this problem we will have extra slow connection instead of ultra fast.

    Is this issue of yours ever been resolved?

    iOs 5.1.2 never existed and I just encountered this problem on iOS 6. Also already 2nd SIM-card in the new iPad (3rd generation) Thought it was the 1st german provider. Now I've got a different one but doesn't work reliable :-(

     

    Guess I should have bought the one without SIM and should have used any mobile with private hotspot <- more reliable

    CleaverT, we travel from the U.S.  to Cayman every few years for vacation. We are returning this May and are bringing iPad 3rd generation and iPad Mini with us both on AT&amp;T data plans.  Can you tell me if I need to do something special to have a connection on these devices on Seven Mile Beach? I sure do appreciate your help. Thank you.
