Can you use your phone on same network on which your phone was Blocked?

When you purchase any phone which is "in contract" with your carrier, there can be several reason for which your phone can be blocked during your contract term. Main reasons for your phone being blocked are: - Late bill payment (you will receive several notifications to pay your bill before they mark your phone as blocked) - Your phone was listed as lost or stolen and you received a new phone in your warranty period from retailer or carrier - Your phone was damaged during your contract period and you received a new phone from your manufacturer, carrier or retailer during your warranty period. Your old damaged phone may be listed as blocked. There can be additional reason why your phone may be listed blocked by your network. Usually these conditions vary with country and network rules. If you phone gets blocked, there are services that will unlock a blocked the phone. Do note that not all blocked phones can be unlocked.  For a list of blocked phones that can be unlocked, click here: www.Jailbreakwizz.com When you purchase a service to unlock your blocked phone and you phone gets unlocked, most of the times you will not be able to use your phone with the carrier that you were locked with. For eg: if your phone was locked with T-Mobile and it gets blocked.  Then you purchase an unlock code for you T-Mobile blocked phone and we unlock it for you.  Your phone is considered unlocked but you will not be able to use that phone with T-Mobile. In the T-Mobile database, your phone is still considered locked.  However, you can take that phone and use it with any GSM network around the world.

        

If you are buying a used phone on Ebay any 3rd party, do ask the seller if the phone was ever barred/blocked/blacklisted by your network. These are terms that are used interchangeably but mean the same thing.  What sometimes happens if you are buying a used phone from auction network is that the phone could have been blocked and unlocked afterwards.  If the phone was blocked by AT&T and subsequently unlocked, this means that you cannot use that phone on the AT&T network. Another more concerning issue is that when buying a used phone, the seller may not mention that the phone is blocked and he may have never unlocked it. This means that you will not be able to use that phone at all unless you get that phone unlocked. Unlocking a blocked phone can be more costly than a clean IMEI and may also take more time.

How to check if a phone is unlocked?

When you get physical access to a phone that you bought, you can simply remove the old SIM and put in your own GSM SIM to check if the phone is unlocked. This assumes that the phone in question is on  a GSM network. When you put in your working SIM into another phone, you should see the signal bars some on and even be able to make calls.  Even some CDMA phones have all GSM frequencies unlocked.  For example, and iPhone locked with Verizon works on a CDMA network but when unlocked, you can use it with any GSM network around the world.
