So one of the things I want to comment on is the discovery of infidelity since I hear that way too often on my radio program. The pain and shock of finding out your spouse has fooled around on you is one of lifeâs most traumatic events. Itâs seriously a punch in the gut.
Whereas a locked cell phone will only accept SIM cards from its current provider, an unlocked cell phone will accept a SIM card from any service provider. (This is very useful if you want to use your phone abroad, for example.) To identify an unlocked cell phone, follow these steps.. Power down your cell phone, remove the battery cover and battery, then look for the SIM card. 1  If you cannot find a SIM card in the back, look for one in the side or top of the phone.
For example, if AT&T paid for the phone, AT&T would lock it so it could only be used on AT&T and not T-Mobile. This lock is called by several names including: Sub Lock or SPC Lock or Sim Lock. Now that you know why the cell phones are locked, I will discuss how to tell if your cell phone is locked or unlocked. First, you must determine if your phone is a GSM phone or a CDMA phone. This is easy to tell, if the phone uses a sim card (a small piece of plastic that you put in the phone, see picture below), it is GSM, if it doesn't, it is CDMA.
