All providers in the U.S. are governed by the FCC number portability rules/protocol. Straight Talk is required to release your number if all conditions are met ...or any mobile provider or carrier for that matter.
One of the main conditions is that your service MUST be active in order to "port" your phone number. Therefore, as long as your current service is active, and your new provider has service in the same area, your old provider is required by law to release your number to the new provider/carrier.
Many Straight Talk customers who decide to move to another provider, let their service lapse because they do no want to move while their service is still active. If you let your service --or your 30-days on the $45 Plan-- lapse, then Straight Talk is not required to release your number. If you read their Terms and Conditions of Service, you will see that technically, you "can" lose your phone number as soon as you let service lapse.
You may have to forfeit a some prepaid service in order to accommodate the port but that is the "cost" of porting. If you transfer to another provider on the 29th day of your 30-day $45 Plan, you can very well run into problems too. I'd suggest doing it at least a week before your plan expires.
I know many former Straight Talk customers who have successfully ported their number to another mobile provider. I personally don't believe the 99% failure figure that stephaniej2888 asserts.
So to others reading this, no matter who your current provider/carrier might be, you MUST have ACTIVE service in order to transfer or port your number to another provider. Your current provider is required by law to release your number if all conditions are met ... and the biggest condition that is usually NOT met and why many have trouble porting is that the let their CURRENT SERVICE LAPSE. Once service lapses, your phone number is technically toast.
Ed, be sure to check with the Straight Talk BYOP website and work through the process to see if your phone is compatible. Many Verizon phones (actually, many CDMA phones) are not compatible.

yes you can, but be warned, if you ever decide to leave straight talk there is a 99% chance you wont be able to take your number with you. I have had so many issues its not even funny and there customer service is awful. I decided to switch from ATT and couldnt get them to release my number and ATT says thats how it is the majority of the time with Straight Talk.
