Keep your U.S. number without keeping an expensive U.S. mobile plan.
Preserve the U.S. number first; replace the service separately.
When I moved from the United States to the Philippines, one thing I did not want to lose was my U.S. phone number.
That number was already tied to banks, credit cards, retirement accounts, two-factor authentication, family, friends, and years of personal contacts. Changing it would have created a lot of unnecessary work.
At the same time, I did not want to keep paying for an expensive U.S. mobile plan that I no longer needed.
My solution was to port my T-Mobile number to Google Voice before leaving the United States. One year later, it has worked extremely well for me.
The main lesson: Do not cancel your U.S. number just because you are moving overseas. First decide whether preserving it will make your financial accounts, security codes, and personal communications easier to manage.
Why I Chose This Setup Instead of Keeping a U.S. Carrier
Cost was a major reason I chose Google Voice.
I had already used T-Mobile internationally during a trip to Thailand and ended up purchasing additional international data after my first allotment ran out. Before moving to the Philippines, I compared the cost of continuing with a major U.S. carrier against preserving my number and using a local Philippine SIM.
Google Voice charged me $20 once to port my existing U.S. number. After that, I have paid no monthly fee to keep that number.
KEEP THE NUMBER · REPLACE THE SERVICE
One number. Two separate decisions.
My setup
Google Voice + Philippine SIM
$20 one-time port fee. $0/month to retain my U.S. number. Philippine service is paid separately.
Major U.S. carriers
Verizon's international monthly plan is $100 per month per line. AT&T's International Day Pass can add up to $120 in a billing period for frequent use.
T-Mobile's 30-day high-speed international pass costs $50 on top of an eligible U.S. plan, and T-Mobile says international roaming is intended for travel rather than long-term residence abroad.
Low-cost U.S. alternatives
Ultra Mobile has a $3-per-month PayGo plan. Tello and US Mobile offer plans around $8 per month.
Those may be worth considering if one of your banks requires a traditional mobile number instead of a VoIP number.
No affiliate relationship. PEG does not earn a commission from Google Voice. I recommend this setup because it is what I use and because it has saved me money.
But for my own accounts, Google Voice has worked. After one year, I still receive the calls, texts, and verification codes I need, while my Philippine SIM handles local service and mobile data.
For me, this was the lowest-cost practical setup I found—and PEG earns nothing from recommending Google Voice.
Do the Port Before You Leave the United States
This is one part I would plan carefully. I started the Google Voice port process shortly before leaving the United States. My goal was to keep my existing T-Mobile number active long enough for Google Voice to take control of it.
Google specifically warns users not to cancel the existing mobile plan until Google Voice confirms that the port is complete. If you cancel the old service first, you could jeopardize the number you are trying to preserve.
Do not cancel your U.S. phone plan before the port is finished. The order matters: port first, confirm completion, then close out whatever remains with the old carrier.
SAFE SEQUENCE
The 5-Step Porting Process
- Check eligibilityConfirm that your number is eligible to port.
- Start the portFollow Google's current porting instructions.
- Keep service activeKeep your existing U.S. service active.
- Confirm completionWait for confirmation that the port has completed.
- Cancel old serviceOnly then deal with cancellation or closure of the old mobile service.
Do not improvise this at the last minute without understanding the sequence. In my case, the timing worked well because much of the transfer occurred while we were traveling.
What Happened When We Arrived in Manila
When we landed in Manila, we needed local Philippine mobile service. At the airport, I bought a Smart SIM card. The staff installed it in my phone and helped set it up. I was able to start using local mobile service almost immediately.
Today I use Globe locally rather than Smart, but the basic setup is the same. My Philippine carrier handles my local mobile data and everyday connectivity when I am away from Wi-Fi. Google Voice keeps my old U.S. number alive.
TWO NUMBERS. TWO JOBS.
U.S. Number
(Google Voice)
- U.S. calls and texts
- 2FA where supported
- Account continuity
- Family, personal, and business contacts
two roles
Philippine SIM
- Local calls and texts
- Mobile data
- Local apps and services
- Everyday Philippine use
How I Use My U.S. Number Today
The biggest advantage is that people in the United States did not have to learn a new number. Family and friends can still call the same U.S. number they have always used. It rings through to me here in the Philippines.
I can also receive calls, make calls, send and receive texts, receive security codes, communicate with banks and credit-card companies, and continue using the number for accounts that were already tied to it.
A Local Philippine SIM Still Matters
Keeping a U.S. number does not remove the need for local service. You will still want a Philippine SIM or eSIM for mobile data, local calls, local text messages, navigation, Grab, delivery drivers, restaurants, landlords, healthcare providers, repair technicians, and other local contacts.
When I am outside my home Wi-Fi, my Philippine mobile service is mainly about data. I use it for navigation, browsing, Facebook, news, messaging, and other normal phone use.
My Two-Factor Authentication Has Worked
This was probably my biggest concern before moving. A phone number is no longer just a phone number. For many people, it is part of the security system for their financial life.
I currently use my old U.S. number for two-factor authentication with several institutions. In my own experience, it has worked with Capital One, Charles Schwab, Citibank Visa, Discover, and the other accounts I personally use that send verification codes.
One year later: I have been using the setup for a full year without a 2FA failure on the services I rely on. That is important firsthand evidence. But it is not a guarantee that Google Voice will work for every reader.
Important: Some Banks May Reject Google Voice Numbers
Google itself warns that some banks and subscription services may not send verification texts to Google Voice numbers. That is because some institutions treat Google Voice as a VoIP number rather than a traditional mobile number.
So even though it has worked flawlessly for my own accounts, I would never tell someone that Google Voice will definitely work with their bank. You need to verify that yourself.
Check your critical accounts before you port
- primary bank and backup bank
- credit cards, brokerage accounts, and retirement accounts
- email recovery and government accounts
- insurance accounts and password managers
- any service that depends on SMS verification
The right question is not whether Google Voice works with banks in general. The right question is whether Google Voice will work with the specific institutions you use.
If I were doing this again, I would make a simple account list before leaving the United States. For each important account, I would record the account name, current phone number, how two-factor authentication works, whether SMS is required, whether an authenticator app is available, whether email recovery is available, and whether a backup phone number can be added.
Useful backup methods, where supported, include authenticator apps, backup codes, email verification, a security key, and an alternate trusted number.
What It Has Cost Me
For the U.S. number itself, my Google Voice port cost about $20 one time, and my monthly cost to keep the number on the no-charge personal Google Voice plan is $0. I separately pay for whatever Philippine mobile service I choose.
I am not maintaining a full U.S. wireless plan just to preserve an old number. I preserved the number and replaced the service.
One Year Later: Would I Do It Again?
Absolutely. As of this writing, I have now lived in the Philippines for one year. During that year, my Google Voice setup has worked for me without any meaningful problem.
I still have the same U.S. number. My family can call it. My friends can call it. My banks recognize it. My credit-card verification messages arrive. My retirement account verification works. And I am not paying a monthly U.S. mobile bill just to keep the number alive.
Who This Setup May Not Be Right For
I would not assume Google Voice is automatically the best option for everyone. It may not be appropriate if your number cannot be ported, a critical bank rejects VoIP numbers, you need traditional U.S. mobile roaming, you frequently return to the United States and want normal domestic cellular service, your employer requires a traditional U.S. mobile line, or you depend on services that specifically require a mobile-carrier number.
The goal is not to convince everyone to use Google Voice. The goal is to show that keeping your U.S. number does not necessarily mean keeping an expensive U.S. mobile plan.
What I Would Do Before Moving
- Identify critical accountsEspecially banks and security systems.
- Confirm portabilityDo not assume.
- Check 2FA compatibilityEspecially for financial institutions.
- Add backupsAuthenticator apps, email, backup codes, or another trusted number.
- Start while in the U.S.Follow Google's current instructions.
- Do not cancelWait for Google to confirm the port.
- Confirm calls and textsBefore considering the process finished.
- Get local Philippine serviceSIM or eSIM depending on your phone and carrier preference.
- Keep both numbersU.S. continuity. Philippine daily life.
My Final View
Your phone number may be one of the least exciting parts of planning an international move. It can also be one of the most inconvenient things to lose.
For me, paying a one-time fee to preserve the number and then using a Philippine carrier for local service was far more practical than continuing to pay for an American mobile plan I no longer needed. After one year in the Philippines, I would make the same decision again.
The most important advice: Do not cancel your U.S. phone service until you have decided what will happen to the number attached to your financial life. A little planning before you leave can prevent a lot of problems after you arrive.
