Android eSIM setup is not identical across manufacturers. Samsung may call the menu SIM Manager, while Pixel commonly places it under Network & Internet.
The phone must support eSIM and be carrier-unlocked. A camera that reads QR codes does not prove that the device can download an eSIM.
Check the exact model and regional version before purchase.
Quick answer: Open the phone’s SIM or mobile-network settings, choose Add eSIM or Download SIM, scan the private QR code once and label the line Brazil. After arrival, select it for data and enable roaming on that line.

Samsung Galaxy Setup
- Open Settings > Connections > SIM Manager.
- Choose Add eSIM.
- Scan the QR code or use the supplied activation details.
- Label the plan Brazil.
- After landing, select it for Mobile data and enable Data Roaming.
Google Pixel and Other Android Phones
On Pixel, look under Settings > Network & Internet > SIMs and Add SIM. Other brands use different wording. Follow the current menu for the exact device, not screenshots from another manufacturer.
Prevent Home-SIM Data Charges
Disable automatic mobile-data switching and keep roaming off on the primary SIM. Calls and messages on the primary line may still have fees. Test the Brazil line with Wi-Fi switched off.
Android Troubleshooting
Refresh Airplane Mode, restart once and leave network selection on Automatic. If manual APN entry is required, create or select the travel profile with data.esim. Do not copy domestic-operator settings or delete the eSIM.
Verify the Exact Android Model Before Buying
Android eSIM support cannot be confirmed from the brand or phone-family name alone. Two devices sold as the same Galaxy, Pixel or Motorola series can differ by model number, sales region, carrier firmware and SIM configuration. Open About Phone, record the full model number and compare that exact variant with the eSIM-compatible devices list.
Look for an EID in About Phone, Status Information or SIM Status. An EID is useful evidence that the device contains eSIM hardware. Also open the SIM settings and check for Add eSIM, Add Mobile Plan or Download SIM. A standard QR-code scanner is not enough: almost any modern Android camera can read a QR code, but only compatible system software can provision an eSIM.
The phone must also be carrier-unlocked. A device can show the Add eSIM menu and still reject a plan from another provider because of a carrier restriction. If the lock status is unclear, ask the original carrier before purchase. NoveSIM cannot remove a lock imposed by that carrier.
Install on a Samsung Galaxy
- Connect the Galaxy phone to stable private Wi-Fi.
- Open Settings > Connections > SIM Manager.
- Choose Add eSIM, then select the QR-code option.
- Scan the private NoveSIM code once or use the supplied manual details.
- Wait for the plan to appear in SIM Manager.
- Rename it “Brazil” so it is distinct from the primary SIM.
- Do not remove it merely because it shows no service before arrival.
Samsung menu names can change between One UI versions and regional firmware. If the expected control is absent, search Settings for “SIM Manager” or “eSIM” rather than installing an unofficial provisioning app. A carrier-specific Galaxy variant may have restrictions not present on an otherwise similar international model.
Install on a Google Pixel
- Open Settings > Network & Internet > SIMs.
- Choose Add SIM or Add eSIM.
- Select the option to download a SIM instead.
- Scan the QR code once and allow the download to finish.
- Open the downloaded line and label it “Brazil.”
- Keep it installed until the trip is complete.
Pixel wording varies by Android release. If the phone uses two active lines, review which line handles calls, messages and data. Do not assume the new plan automatically becomes the data line when it is switched on.
Other Android Manufacturers
Motorola, Xiaomi, Oppo, Honor and other manufacturers place eSIM controls in different menus, and only selected models or regional variants support the feature. Look under Network & Internet, Mobile Network, Connections, SIM Cards or SIM Manager. Use the manufacturer’s current instructions for the exact model rather than forcing a Samsung or Pixel path onto another interface.
If the order includes manual activation information, enter it only in the Android system’s eSIM setup flow. Do not paste the activation code into a general QR app, browser form or third-party “SIM manager.” Protect both the QR image and manual code as private credentials.
Installation Is Not the Same as Activation
Installation downloads the profile. Activation follows the exact product rule, and connection occurs when the phone registers on a supported network. A Brazil eSIM may therefore appear correctly in Android while showing no service in another country.
Read the Brazil activation guide and the order instructions before switching it on during an earlier stopover. Some plans begin validity on first eligible network connection; others can follow a different trigger. Generic advice cannot replace the rule stated for the purchased product.
Recommended Android Settings After Landing
| Android setting | Recommended choice | Why |
|---|---|---|
| Use SIM / Enable line | Brazil on | Allows registration on the partner network |
| Preferred SIM for mobile data | Brazil | Keeps app data on the travel plan |
| Roaming on Brazil line | On | Travel eSIMs normally use partner roaming |
| Roaming on home line | Off | Reduces unintended home-carrier data |
| Automatic data switching | Off | Prevents fallback to the home SIM |
| Network selection | Automatic | Allows normal partner selection while travelling |
| Preferred network type | Automatic 5G/4G | Avoids forcing an unavailable technology |
Some phones call automatic switching “Switch mobile data automatically,” “Backup calling,” “Data switching” or “Adaptive connectivity.” Review the description before changing it. The goal is to prevent the device from moving data to the primary line when the Brazil connection weakens.
Keep Your Number and Messaging Apps
NoveSIM Brazil plans are data-only and do not include a Brazilian telephone number, conventional calls or SMS. WhatsApp, Signal, Telegram and other internet services can use the travel data while remaining registered to the existing number. Do not accept a prompt to change the WhatsApp number unless an account migration is intentional.
The primary SIM can often stay active for calls and messages, but its carrier may charge for answered calls, voicemail or roaming services. Selecting the Brazil eSIM for data does not change those rates. If the goal is to avoid all primary-line charges, ask the home carrier which services must be disabled.
Set the APN Only When It Is Needed
Most Android phones receive APN settings automatically. If the device has network signal but cannot load any page and the plan instructions require manual entry, open the Brazil line’s Access Point Names menu and create or select the travel entry. Use data.esim exactly for the APN, leaving username and password blank unless instructed otherwise.
Do not copy an APN from Claro, TIM, Vivo or another travel-eSIM provider. Those values belong to different services. An APN also cannot repair a no-signal area because it controls data routing only after radio registration. The Brazil APN guide separates these symptoms.
Network Selection and Brazil Coverage
Keep selection on Automatic for normal use. If registration repeatedly fails, manually test only a network supported by the exact plan and allow several minutes for each attempt. The scan can show operators that are visible but not authorised. Return to Automatic when moving to another city or route.
Coverage depends on location, terrain, buildings, partner access and the phone’s radio bands. A 5G-capable Android device does not guarantee 5G everywhere, and forcing 5G can waste battery or reduce stability. Use the Brazil coverage guide before remote road, island or Amazon travel.
Manage Battery and Mobile Data
Android can restrict background data by app and mark a connection as metered. Before travel, pause cloud photo backup, automatic Play Store updates, operating-system downloads and large media synchronisation. Reset or note the phone’s data-use counter when the plan begins.
Weak-signal searching and hotspot use consume battery. Carry a power bank for long transfers and stop repeated speed tests when coverage is poor. Estimate the allowance with How Much Data for Brazil and verify any fair-use or hotspot terms on the exact product.
Safe Troubleshooting on Android
- Confirm that the Brazil profile is present and switched on.
- Select it as the preferred SIM for mobile data.
- Enable roaming for Brazil and disable data switching.
- Turn off Wi-Fi and test a normal webpage.
- Toggle Airplane Mode for about 30 seconds and wait.
- Restart once if registration does not change.
- Check validity, allowance and APN when signal exists without data.
Do not reset all network settings or delete the eSIM as early steps. A reset can remove saved Wi-Fi networks and other configuration, while deletion can make a one-use activation code impossible to reuse. Follow Brazil eSIM troubleshooting and contact support with the order number, model, location and safe screenshots if the problem persists.

Final Recommendation
Verify the exact Android model, regional eSIM support and carrier-unlocked status before purchase. Install the profile once through the phone’s system settings on reliable Wi-Fi and keep its credentials private.
After arrival, switch on Brazil, choose it as the preferred data SIM, enable roaming on that line and turn off automatic switching to the home SIM. Keep network and radio selection on Automatic for normal travel.
If data fails, diagnose the displayed symptom before editing APN or network settings. Use reversible checks, keep the eSIM installed and send the precise model, location and safe screenshots to support when the documented sequence does not restore service.
