How to Switch Phone Carriers Without Losing Your Number
A complete guide to porting your number, unlocking your phone, and making a seamless switch. Takes 15 minutes.
Switching carriers used to be a nightmare. In 2026, it takes about 15 minutes. Here's exactly how to do it.
Before You Switch
1. Check your device — Make sure your phone is unlocked and compatible with the new carrier's network. Most phones from the last 3 years work on all networks.
2. Get your account info — You'll need your account number and PIN/passcode from your current carrier. Find these in your online account or call customer service.
3. Don't cancel first — Keep your current service active. Porting your number automatically cancels the old account.
The Switch Process
Step 1: Order a SIM or eSIM from your new carrier. Many carriers offer free SIM kits or instant eSIM activation.
Step 2: When activating, choose "transfer existing number" and enter your old carrier's account number and PIN.
Step 3: Wait 5-30 minutes. You'll get a text or notification when the port completes.
Step 4: Your old service cancels automatically. You may get a final bill.
Common Issues
- Port stuck? Call the new carrier, not the old one
- No service? Restart your phone after porting
- Wrong account info? The #1 reason ports fail — double-check your account number and PIN
Pro Tips
- Switch mid-billing-cycle to avoid paying for a full month on both carriers
- Download your old carrier's app to grab your final bill
- Test the new carrier's coverage for a few days before porting if possible
