Switching eSIM networks on an Android device in Sri Lanka is usually a straightforward process, but it requires careful preparation because the steps can vary by phone model, Android version, and mobile operator. A person may switch from one eSIM profile to another for better coverage, lower data costs, travel convenience, business separation, or improved network performance. The most important requirement is that the Android phone must support eSIM, be network unlocked, and have a valid eSIM profile from a Sri Lankan operator that offers eSIM service.
TLDR: To switch eSIM networks on an Android device in Sri Lanka, the user must first confirm that the phone supports eSIM and is unlocked. They then need to obtain a new eSIM QR code or activation details from the chosen operator, add the profile through the Android SIM settings, and select it as the preferred network for calls, SMS, and mobile data. After activation, the user should test signal, data, calls, SMS, and APN settings before deleting any old eSIM profile.
Understanding eSIM Switching on Android in Sri Lanka
An eSIM, or embedded SIM, is a digital SIM built into a device. Unlike a physical SIM card, it does not need to be inserted into the phone. Instead, the network profile is downloaded to the device, usually by scanning a QR code or entering activation details provided by the mobile operator.
In Sri Lanka, eSIM services are generally associated with major mobile operators and selected supported plans. Availability may depend on whether the customer is using a prepaid plan, postpaid plan, tourist plan, corporate connection, or data-only service. Because operator policies change from time to time, the user should always confirm eSIM availability directly with the chosen provider before starting the switch.
Switching eSIM networks does not always mean deleting the previous eSIM. Many Android devices can store more than one eSIM profile, although only one or two SIM connections may be active at the same time depending on the model. This allows the user to keep one network inactive while testing another.
Step 1: Check Whether the Android Device Supports eSIM
The first required step is checking device compatibility. Not all Android phones support eSIM, even if they are modern smartphones. Popular Android devices from Google Pixel, Samsung Galaxy, Motorola, and selected other brands may include eSIM support, but the feature can vary by country, model number, and firmware.
The user can usually check for eSIM support in one of the following ways:
- Opening Settings and searching for eSIM, SIM manager, or Add mobile plan.
- Going to Settings > Network & Internet > SIMs on many Android phones.
- Going to Settings > Connections > SIM manager on many Samsung Galaxy devices.
- Dialing *#06# and checking whether an EID number appears. The EID is commonly linked to eSIM capability.
- Checking the phone manufacturer’s official specifications for the exact model number.
If the phone does not show an EID or any option to add an eSIM, it may not support eSIM. In that case, switching to another eSIM network will not be possible on that device, and a physical SIM or a different phone may be required.
Step 2: Confirm That the Phone Is Network Unlocked
The next step is confirming that the Android device is unlocked. A locked device may only work with the original operator or region. This is especially important for phones purchased overseas, imported devices, installment-based phones, or operator-branded phones.
If the device is locked, it may reject the new Sri Lankan eSIM profile or fail to connect after installation. The user can check this by contacting the original seller, checking the device purchase agreement, or trying another operator’s physical SIM or eSIM if available. If the phone is locked, it must usually be unlocked by the original carrier before switching networks.
Step 3: Compare Sri Lankan eSIM Network Options
Before changing networks, the user should compare available eSIM plans in Sri Lanka. Coverage and performance can differ significantly between Colombo, Kandy, Galle, Jaffna, rural areas, coastal towns, and hill country regions. A network that performs well in one location may be weaker in another.
Important factors to compare include:
- Coverage: Signal strength in the user’s home, workplace, travel routes, and rural destinations.
- Data speeds: 4G and 5G availability where supported by the device and operator.
- Plan type: Prepaid, postpaid, tourist, business, or data-only options.
- Call and SMS requirements: Whether the user needs a local number for banking, delivery apps, or two-factor authentication.
- Roaming support: Useful for Sri Lankans traveling abroad or visitors moving on to other countries.
- Customer support: Availability of online activation, service centers, and replacement QR codes.
For someone living in Sri Lanka, local network reliability may matter more than the cheapest package. For a visitor, a short-term eSIM with generous data may be more practical. For a business user, stable calls and SMS may be just as important as data.
Step 4: Obtain the New eSIM Profile
After choosing a network, the user must obtain a new eSIM profile from the selected operator. This usually involves purchasing a plan or requesting conversion from a physical SIM to an eSIM. The provider may supply the eSIM through a QR code, in-app activation, email, printed voucher, or manual activation code.
In Sri Lanka, identity verification may be required, especially for local mobile numbers. The operator may ask for official identification, passport information for visitors, address details, or existing account information. For postpaid accounts, additional verification may apply.
The user should keep the QR code safe and private. An eSIM QR code can sometimes be used only once, and sharing it may create security risks. If activation fails or the device is reset, the user may need to request a replacement from the operator.
Step 5: Prepare the Android Phone Before Switching
Before adding the new eSIM, the user should prepare the phone to avoid interruptions. The device should be connected to stable Wi-Fi because the eSIM profile must be downloaded from the internet. The battery should be sufficiently charged, and the phone should not be restarted during activation unless instructed.
The user should also review the current SIM setup. If the existing eSIM is being used for banking alerts, WhatsApp, work calls, or two-factor authentication, deleting it too early may cause problems. A safer approach is to install the new eSIM first, test it, and only then remove the old profile if necessary.
It is also useful to back up important phone data and note the current APN settings. Most networks configure APN settings automatically, but manual entry may occasionally be needed for mobile data or MMS.
Step 6: Add the New eSIM on Android
The exact menu names differ between Android brands, but the general process is similar. On many Android phones, the user can add an eSIM by following these steps:
- Open Settings.
- Go to Network & Internet, Connections, or SIM manager.
- Select SIMs, Mobile network, or Add eSIM.
- Choose Download a SIM, Add mobile plan, or Scan QR code.
- Scan the QR code provided by the Sri Lankan operator.
- Confirm the plan details and wait for the phone to download and install the eSIM.
- Restart the device if the operator or phone recommends it.
On Samsung phones, the path is often Settings > Connections > SIM manager > Add eSIM. On Google Pixel phones, it is often Settings > Network & Internet > SIMs > Add SIM. Other Android brands may use slightly different wording, but the eSIM option is usually found under network or SIM settings.
Step 7: Select the Preferred eSIM Network
After installation, the new eSIM may appear as an additional mobile plan. The user should rename the profile to avoid confusion. For example, the profiles can be labelled Work, Personal, Sri Lanka Data, or with the operator name.
The user must then choose which SIM or eSIM will be used for each service:
- Mobile data: The eSIM selected here will provide internet access.
- Calls: The preferred SIM for outgoing voice calls can be selected.
- SMS: The preferred SIM for text messages can be selected.
- Default number: Some phones allow one SIM to be set as the main line.
If the old SIM remains active, the phone may operate in dual SIM mode. However, some Android devices cannot keep two eSIMs active at the same time, even if they can store multiple eSIM profiles. The user may need to turn one profile off before activating another.
Step 8: Test Calls, SMS, and Mobile Data
Once the new eSIM is selected, proper testing is essential. The user should check whether the phone displays signal bars and the correct operator name. They should also verify whether 4G, LTE, or 5G appears where available.
A complete test should include:
- Opening a website or speed test app using mobile data.
- Making an outgoing call to a local number.
- Receiving an incoming call if voice service is included.
- Sending and receiving SMS messages.
- Checking apps that require mobile verification, such as banking or delivery apps.
- Testing hotspot or tethering if it is needed and allowed by the plan.
If data does not work, the user should check whether mobile data is assigned to the new eSIM. If calls or SMS do not work, the user should confirm that the plan includes those services and that activation is complete.
Step 9: Check APN and Network Settings
Most modern Android phones automatically receive APN settings from the operator. However, if mobile internet does not work after activation, the APN may need to be checked manually. The user can usually find APN settings under Settings > Network & Internet > SIMs > Access Point Names or a similar menu.
The correct APN details should come from the operator’s official support page or customer service. Random APN settings found online may be outdated or insecure. The user should also check that data roaming is enabled only when necessary, especially if the eSIM is used while traveling outside Sri Lanka.

Once the new eSIM is working reliably, the user can decide whether to keep, disable, or delete the old eSIM profile. Disabling is usually safer than deleting because the profile remains stored on the device. Deleting may permanently remove the profile, and reactivation might require a new QR code or a visit to the operator.
The old eSIM should not be deleted if it is still needed for account recovery, banking messages, roaming, business contacts, or number portability. If the user is transferring a number from one operator to another, they should wait until the porting process is fully completed and confirmed.
Common Problems When Switching eSIM Networks
Several issues may occur during the switching process. If the QR code does not scan, the user should improve lighting, clean the camera lens, enlarge the code on another screen, or enter the activation details manually if available. If the phone says the eSIM cannot be added, the device may be locked, unsupported, or already assigned too many eSIM profiles.
If the eSIM installs but does not connect, airplane mode can be turned on and off, or the device can be restarted. The user should also confirm that the correct eSIM is enabled and selected for mobile data. If none of these steps work, the operator may need to refresh activation from their side.
Security and Practical Tips
eSIM profiles should be treated like sensitive account credentials. The QR code should not be posted online, sent to unknown people, or stored in an unsecured location. If the phone is lost, the user should contact the operator quickly to suspend the eSIM.
For people frequently moving between areas in Sri Lanka, keeping more than one SIM option can be helpful. One network may offer better coverage in urban areas, while another may perform better in rural or coastal regions. Android’s SIM manager allows users to switch data lines without physically opening the phone, which is one of the main advantages of eSIM technology.
