What does “porting a line” mean?



June 22, 2016



Officially known as “Wireless Local Number Portability (WLNP)”, porting a line is the process that lets you change carriers but keep your wireless number. Watch out when porting your line because each of the big carriers has different traps if you’re not careful.

AT&TAT&T will cancel your old service for you. The longest they take to transfer a number is 4 hours. They will also keep both your old and new service active until the porting process is complete so you’re never without service.

SprintSprints’ overall process takes 2 to 5 days. During this time your old service will remain active while your new service is activating, AND you will get double billed for 2-5 days. Ask Sprint to credit the time you were with a temporary phone number – all the other carriers take no more than 24 hours to port a phone number.

T-MobileT-Mobile will not cancel your old service for you. T-Mobile’s porting process has typical delays ranging from 5 minutes to 24 hours. If you’re porting multiple lines expect as much as a 10 day delay. Do NOT cancel your old service until your new T-Mobile device(s) can make and receive phone calls, texts and browse online without WiFi.

Which New Verizon Plan is Best for Me?

Unless you’ve been sleeping under a rock, you’ve probably seen either celebrity studded ads for the new plans from Verizon Wireless or scathingly critical articles lampooning Verizon’s price hikes and Twitter campaign. If you’re interested in saving money on your wireless bill, neither of these are of much use. No worries — Wireless Butler is here to help.


Unlimited or Um-limited?

“Unlimited” is the worst example of mislabeling in wireless. All so-called unlimited plans are throttled. That’s why we call them “um-limited.” Here’s what you might have missed in the fine print on your um-limited data plan:
