Porting to Cricket Wireless
You will need to acquire a wireless carrier SIM Card. The most cost effective wireless carrier we found is Ting Mobile. Ting Mobile GSM SIMs are available locally (Best Buy, Target, Walmart, etc.) for approximately $5 to $10. Amazon has them as well. Direct purchase from Ting Mobile online is another option but may take 3-5 business days for shipping. Google Voice charges $20 to port a number in. Additionally, you’ll need access to an unlocked GSM compatible phone to house the Ting Mobile SIM long enough to complete Google’s verification requirements. This phone may be "borrowed". It does not need to be your active cell phone.
Check Ting Rates here. We recommend the single line at $6. Google Voice will send a call and text for verification. This will count as 1 or 2 minutes falling into Ting’s 1-100 usage minutes for an additional charge of $3.
