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.

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

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.

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

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.

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
