hi, ok.... Model A1387 EMC 2430 FCC ID; BCG-2430A IC; 579C-E2430A.....really appreciate any help on this.... thanks

Weird. The 4s A1387 should work in all major frequencies. They never made a specific CDMA or US version. However they did sell some models in the US late 2012 till now that if unlocked had the CDMA frequency blocked. Bit AIS is not using that type of network.

Have you tried other AIS SIM cards? Maybe sim is broken. Alternative the phone is faulty and only the band used by AIS doesn't work, but that sounds very unlikely.

Have tried 2 different AIS sims, both of which did not work.... sounds like the phones broken then.....

So..if the phone's faulty, can i take it to any Apple shop to get it fixed, it's les than 1 yr old, how does that work out warranty wise in the LOS ?
