Mark's wife got a mobile phone through Verizon and he had it unlocked to use with an MVNO carrier, but it doesn't work. Leo says that it could be due to radio frequency issues. Leo says that unlocking doesn't guarantee that he'll be able to use the phone anywhere. But it's the first step. That's why everyone is going to LTE. That will smooth out the system and make it easier to transfer from one carrier to another.
John would like to keep his legacy phone number and just use it for voicemail. Leo says he can port his phone number to a service, and he likes Grasshopper. There's also Google Voice, but John says that they won't port landline numbers. When he does port his number to a service, he will no longer have a landline phone, so he should keep that in mind.
Michele and her husband split up and now suddenly, her phone has been turned off. Leo says that her husband's account means he owns the number. Leo says that she could go to T-Mobile, set up a new account, and get a new SIM and number.
