Techguy is right.
Here's the deal. If you load a Cricket PRL and you set an SPC on the older Samsungs OTHER than 000000, your phone WILL start to OTA with *228 and of course fail when trying to do the SPL unlock part of the OTA.
If you set the SPC to 000000, the phone will go to Sprint when you dial *228. But if you dial the *228xx nuraber it will OTA correctly and since it is unlocked (000000) it will succeed in programming automatically and oddly enough if you look at your last call it shows you dialed *2.
What I do with these phones is to dial the *228xx code and tell the customers to redial the call that says "*2 Customer Service". That way they can still OTA the phone and I don't tell them what the *228xx code is. Not that it makes much difference if they are reading this right now. LOL.
The A900 is even a little wierder. I load the Cricket PRL and set the SPC to 000000.
When you dial *228 and hit "talk" it goes back to the start screen. When you start dialing *228 again you will see *228*228. In other worRAB the *228 is still there from the last dial.
So what I do on the A900 is really similar to other Samsungs (a660, a680, a840, etc.), I dial *228 and "talk" and it goes to the start screen. I then dial the last part of the *228xx code, which for Denver is 07. So now I see *22807. Then I hit "talk" and it goes to the Cricket OTA song.
When you look at your dialed calls, you will see *2 Customer Service.
If you redial it, it goes to the Cricket OTA.
I have not tried *2 on the newer Sprint or Qwest phones. It might work for those but definitely will not work for older Samsung phones. *2 and *228 goes to Sprint even with a loaded Cricket PRL.
The NAM settings that are in the phone are irrelevant and as stated before, when you get a successful OTA, they get changed automatically.
YES. It is definitely a Sprint firmware issue. I have done some Verizon Samsungs and they go to Cricket OTA when dialing *228.
If you look at the PRL interpretations, you will see in what block Cricket operates in your area. For example: 5458 SID is Denver and it operates on the F block of the 1900 spectrum. The block is usually after the channel nuraber. For example: 825F 875F
The following will help determine which *228 (*ACT) code to use for your block.
*22802 = A block
*22803 = B block
*22804 = C block
*22805 = D block
*22806 = E block
*22807 = F block
If the *228xx codes do not work in your area, then you are SOL for doing the above or trying to program an unlocked phone with OTA. Your only solution is manual PRL loading and showing customers how to manually program the phones.
