Google Voice uses prepaid credit for calls to real phone numbers
Google Voice itself is free to use for calls and texts between Google Voice accounts and to US phone numbers over WiFi or data. But when you call a real phone number outside the US, or use Google Voice on a phone that doesn't have data, you need prepaid credit. You add this credit through your Google Account payment method, and the balance sits in your Google Voice account until you use it.
The process takes about five minutes and requires a valid payment method on file — a debit card, credit card, or Google Play balance. Once you add credit, it stays in your account and doesn't expire as long as you use your Google Voice number at least once every six months.
Key Takeaways
- Google Voice credit is only needed for international calls and calls made without an internet connection, not for calls between US-based Google Voice accounts.
- You add credit through your Google Account settings using a debit card, credit card, or Google Play balance.
- Credit does not expire as long as you place at least one call or send one text from your Google Voice number every six months.
- Rates for international calls vary by country and are shown before you complete the purchase, so you can see exactly what you are paying.
Where to find the credit purchase option
Open Google Voice on a computer or the Google Voice app on your phone. On a computer, click the gear icon in the top right corner and select Settings. On the app, tap the three horizontal lines in the top left, then tap Settings.
In Settings, look for Billing or Credits in the left menu (on a computer) or scroll down to find it (on the app). Click or tap Add credit. You will see a form asking how much credit you want to add, starting at $1 and going up to $50 in a single purchase.
What payment methods Google Voice accepts
Google Voice takes any payment method linked to your Google Account. This includes Visa, Mastercard, American Express, and Discover debit or credit cards. If you have a Google Play balance from gift cards or refunds, you can use that instead of a card.
Google does not accept PayPal, bank transfers, or prepaid cards that are not linked to a major card network. If your card keeps being declined, check that the billing address on your Google Account matches your card's billing address exactly.
How much credit to buy and what it covers
The amount you need depends entirely on where you call. Rates to Canada and Mexico are usually 1 to 2 cents per minute. Rates to India, the UK, and most of Europe range from 2 to 10 cents per minute. Rates to some countries in Africa, the Middle East, and Asia can be 20 to 50 cents per minute or higher.
Before you make a call to an international number, Google Voice shows you the rate for that country. You can see the full rate list by going to Settings and looking for Rates or Pricing. This way you know exactly what a call will cost before you dial. Many people start with $5 to $10 in credit to test the service, then add more if they call internationally often.
What happens when your credit runs out
When your credit balance reaches zero, you cannot make calls to real phone numbers or calls that require internet. Calls and texts between Google Voice accounts stay free. You will see a warning when your balance is low, usually when you have less than $1 remaining.
If you try to call a number and your credit is gone, Google Voice will tell you the call cannot go through and ask if you want to add more credit right then. You can also set up automatic recharging so that credit is added to your account when the balance drops below a certain amount — usually $1 or $5.
How to set up automatic credit recharging
In Settings under Billing or Credits, look for an option called Auto-recharge or Automatic top-up. Turn this on and choose the amount you want added automatically (usually $10) and the balance at which it triggers (usually $1). Once this is set, Google will charge your payment method whenever your balance drops below your chosen threshold.
You can turn automatic recharging off at any time in the same menu. If you do not want to be charged unexpectedly, leave this off and add credit manually when you need it.
What to do if a payment fails
If your card is declined when you try to add credit, Google Voice will show an error message. The most common reasons are a mismatched billing address, an expired card, or insufficient funds. Check that your card's billing address matches exactly what is on your Google Account — even a different apartment number or ZIP code can cause a decline.
If the address is correct, try a different payment method if you have one on file. You can also remove the declined card from your Google Account and add it again, which sometimes fixes temporary processing issues. If the problem persists, contact your card issuer to ask if they are blocking charges from Google.
Frequently Asked Questions
Does Google Voice credit expire?
No, as long as you use your Google Voice number at least once every six months — either making a call, sending a text, or receiving a call. If you do not use the number for six months, Google may close the account and you will lose any remaining credit. Using it once every six months keeps both the account and the credit active.
Can I get a refund for unused credit?
Google does not refund unused credit. Once you add credit to your account, it is yours to use but cannot be converted back to cash or transferred to another account. This is why starting with a small amount like $5 is a good idea if you are not sure how much you will need.
Why does my international call cost more than the rate shown?
The rate Google shows is per minute, and calls are billed in one-minute increments. A 30-second call costs the full one-minute rate. Some countries also have connection fees of 10 to 20 cents added to each call. Check the rate page in Settings to see if your destination country has a connection fee listed.
Can I use Google Voice credit on the mobile app and the website?
Yes, credit is tied to your Google Voice account, not to a specific device or app. Any credit you add is available whether you call from the app, the website, or a phone connected to Google Voice through a third-party service.
