Phone Not Allowed Mm6 Unlock

Unlocking a phone enables you to use your phone on a compatible carrier’s network.

Hey,I have a blackberry 9300 curve and it is saying phone not allowed MM6.please help me unlock it MY PRD:38284-016 IME:15677. Re: Free Blackberry Unlocking Codes With'Imei +prd Code';no More Mep Code(NOT OS10) by femi4: 9:21pm On Jun 05, 2013. After using a CL purchased At&T Galaxy S3 for 14 days, the phone now says 'Phone not allowed MM#6', and does not allow any calls. I verified the IMEI number with T-Mobile and AT&T and the number is not Blacklisted / Reported Stolen (had to confirm this before I tried anything).

Phone Requirements

The phone must be a Metro by T-Mobile Phone.


  • Unlocked phones can only use networks of the same type. For example, an unlocked GSM-only phone will only work with another carrier’s compatible GSM network. It will not work with another carrier’s CDMA network.
  • Unlocking your phone does not guarantee that the phone will fully work with all of a competing carrier’s services and features.

Service Requirements

Your handset must have had active service for a minimum of one hundred eighty (180) consecutive days from the individual phone’s activation date.

Note: For warranty exchange handsets, the original phone’s activation date counts as the beginning of the one hundred eighty (180) days, not the activation date of the warranty exchange handset.

Mobile handsets are sometimes 'locked' to the network from which the handset is purchased. This means the handset will usually only work when used with that particular provider.


If you want to switch to a different provider but keep your existing handset, you may need to get it unlocked.

You may also need to get your handset unlocked if you want to use a local SIM card in your handset when travelling abroad to avoid roaming charges.

Handset locking policies can differ from provider to provider or can depend on the type of device and package being sold to you.

For example, all of EE’s and BT Mobile's, and most of Vodafone’s handsets are sold locked to their networks. Tesco Mobile also locks most of its pay-as-you-go handsets and some of its pay monthly handsets. Sky's, Three’s, Virgin Mobile's and O2's handsets are sold unlocked.

You can find out whether your handset is locked by asking your mobile phone provider, or by trying a different network SIM card in it.

If you get a message that indicates there is a problem and you cannot make calls, it's possible that your phone may be locked.

If your handset is locked you can ask your provider to unlock it for you. Phones reported as lost or stolen will not be unlocked.

Mobile providers have different policies and processes for unlocking phones. For example, some will only unlock your mobile phone after a certain period of time has passed and will charge a fee, while some will unlock your phone at any time for free. If you are on a pay monthly contract and are outside your minimum contract period, most providers will unlock your phone for free.


Some handsets can be unlocked relatively quickly. For other handsets, unlocking may take longer, particularly if your provider has to contact the handset manufacturer to get the unlocking code.

Details of your provider’s handset unlocking procedure will usually be available on their website.
