APN for mobile data
If you are asked for an MNC, 10 is the most common. Some regions also use 06, 11 or 23.
APN for mobile data
Name the APN Claro Dados I and type the APN type in lowercase (default,supl). If there is no type field, tick Internet.
Claro says the APN settings are the same on all phone brands.
Other APNs
Older APN (no longer current)
claro.com.brClaro now uses java.claro.com.br.
We found no separate MMS settings for Claro. Picture messages usually work with the APN above, or your phone sets them itself.
APN for mobile data
Leave the MNC at your phone's default, because it changes by region.
On iPhone, go to Settings > Cellular Data > APN Settings and use the same APN, username and password.

Need a username
The main internet APN for every carrier in one table. The cards above have the full settings, other APNs and the MMS values.
All 3 carriers on this page run their own network. Each one has its own APN, so make sure you copy the settings for the carrier named on your SIM, not the one with the best coverage.
Vivo, Claro and TIM use a username and password in the APN. Type them exactly as shown. Where an authentication type is given: Vivo uses PAP and TIM uses PAP.
Vivo and TIM list separate settings for picture messages (MMS). If texts work but photos in messages do not, those are the values to check. Claro also has a second APN for some plans or devices, shown on its card.
The carriers here use the mobile country code 724, the first three digits of every network code in Brazil. Android usually fills in the MCC and MNC from the SIM, so you rarely need to type them.
Visiting Brazil with your own SIM? Keep your home APN: roaming data still goes through your home carrier. You only need these settings with a local SIM bought in Brazil. Or skip the SIM shop with a Brazil eSIM, which sets its own APN.
iPhone
No Mobile Data Network option? Your carrier locks it, and the iPhone sets the APN for you.
Android
Made a mess of it? Reset to default in the same menu brings the original settings back.
Data and roaming on
Mobile data must be on, and airplane mode off. On a local SIM, data roaming can stay off.
The APN, letter for letter
For Vivo that is zap.vivo.com.br. One wrong dot or capital is enough to block data.
Username only if listed
Only Vivo, Claro and TIM need one here. Leave it blank for the rest.
Select it and restart
On Android, tap the entry so its dot is filled. Then restart the phone and open a website.
Calls and texts work, only data does not? That points to the APN, because calls and normal texts do not depend on it. If nothing works at all, the SIM itself may not be active yet: ask the shop or the carrier.

Each carrier card names its own sources. Checked 2026-10-01.
The Vivo internet APN is zap.vivo.com.br, with username vivo and password vivo.
The Claro internet APN is java.claro.com.br, with username Claro and password Claro. Some plans use a different APN, listed on this page.
The TIM internet APN is timbrasil.br, with username tim and password tim.
Vivo, Claro and TIM use a username and password in the APN. For all of them, leave both fields blank.
Usually not. Your phone reads the APN from the SIM and sets it for you. You only need to add it by hand if mobile data does not work, often after moving a phone between networks or on an unlocked import.
Not if you use your own SIM: roaming uses your home carrier's APN. You only need the settings on this page if you buy a local SIM from a carrier in Brazil.
No. At worst, mobile data or picture messages stop working until you fix it. On Android, Reset to default in the APN menu puts the carrier's own settings back.
A travel eSIM installs before you fly and usually sets its own APN. Pay in crypto, no ID, no email.
