Frequently Asked Questions

eSIM stands for embedded SIM (Subscriber Identity Module). Unlike traditional SIM cards, eSIMs are built into the device, allowing you to activate a mobile plan without needing a physical card.

eSIMs work by storing a mobile carrier profile digitally on the device’s embedded chip. You can activate it by scanning a QR code or entering your carrier settings, enabling seamless connectivity with the local network.

An eSIM is convenient for switching carriers, which is great if you need two phone numbers for work and personal use, or if you’re traveling internationally. It eliminates the need for physical SIM cards, supports dual networks, and saves space in your device.

Yes, you can keep your own phone number with an eSIM. It requires transferring your existing mobile plan to the eSIM through your carrier. If you purchase a new plan, though, you’ll need to check with the specific provider.

Most modern smartphones support eSIM, including the latest iPhones, Google Pixels, Samsung Galaxy, and select Oppo and Huawei models. Check your device’s specifications to confirm compatibility before buying an eSIM. Read more: eSIM-Supported Phones

To transfer an eSIM, you need to first deactivate it on your current device through carrier settings. Then, reactivate it on the new device by scanning the QR code or entering the eSIM details. The exact process for installation can vary depending on the device and the provider.

You can set up an eSIM in just a few minutes by scanning the QR code provided by your carrier. Simply purchase the eSIM, go to your device’s settings, and choose the Add eSIM option. Scan the QR code on the camera, then follow the on-screen prompts to complete the activation. Note that the exact process can vary depending on your device and carrier.

You can activate an eSIM by scanning the QR code from your carrier, or by manually entering the details under your phone’s mobile network settings. It should activate automatically (if you’re traveling, this will happen once you arrive at your destination).

Activating an eSIM typically takes a few minutes, but it can vary depending on the carrier and the signal where you are. Some activations can take up to 24 hours to process, so make sure you allow ample time for worst case scenarios.

eSIM adoption is limited by device compatibility and carrier support–some regions don’t yet have great access for eSIMs. Furthermore, it depends on user awareness. Some users prefer physical SIM cards because it’s what they’re used to, while others don’t yet have an eSIM-compatible device.

No, an eSIM does not weaken the signal. Network strength depends on carrier coverage, not the type of SIM you’re using.

eSIMs offer flexibility, allowing for easy switching between carriers and plans without a physical card. They save space in devices and enable dual SIM functionality, making them ideal for frequent travelers.

Yes, most dual-SIM devices allow you to use an eSIM alongside a physical SIM. So, if you have an eSIM-compatible phone with a physical SIM card slot, you can still install your eSIM and manage both plans at the same time.

Yes, you can store multiple eSIM profiles on one device. However, only one or two can be active at a time, depending on the device.

Yes, eSIMs are as secure as (if not more secure than) physical SIM cards. They are protected by encryption and are harder to remove or clone without access to the device.

eSIMs themselves do not significantly impact battery life. However, using dual SIMs or maintaining multiple active networks simultaneously can drain the battery faster.

If your phone doesn’t have a SIM card slot, then you’re already using an eSIM! eSIMs eliminate the need for physical SIMs, saving space in the device.

If you’re traveling internationally, set up your eSIM at least 24 hours before you travel. That way, you can allow time for the eSIM to activate before you arrive at your destination.

Unused data typically expires when your plan ends, unless your carrier offers rollover data. Always check the plan terms before purchase. 

If you use up all your data, you can either purchase a top-up or continue at a reduced speed, depending on your carrier’s policy. Most often, you won’t be able to use any more data until you renew or top up your plan.

Yes, some carriers offer unlimited data plans for eSIMs, even for international travel. Availability and terms vary by region and provider.

Yes, many international eSIM providers offer plans that work across multiple countries, making them ideal for travelers. Examples include Holafly and Airalo.

Local SIM cards are for use in a specific country or region, offering affordable rates for local calls, texts, and data. International SIM cards provide connectivity across multiple countries, ideal for travelers who need consistent service without swapping SIMs in each destination.

Yes, you can often use your home SIM card abroad, but it depends on your carrier, plan, and your destination. Many carriers offer international roaming at higher costs, which can lead to expensive charges. Check your carrier’s roaming policies before traveling. 

The type of SIM you need depends on your preference. Local SIMs are best for extended stays or frequent data use in one country. Meanwhile, international SIMs are convenient for multi-country trips. Personal SIMs are good for minimal roaming, or if your carrier offers affordable international plans. 

Physical SIMs and eSIMs are equally reliable in most cases. eSIMs offer convenience with remote activation and multiple profiles, while physical SIMs might have wider compatibility in older or less advanced devices. Read more: SIM vs ESIM

If you buy a local SIM for the duration of your trip, you can purchase credit at kiosks, carrier stores, or online. For international SIMs, refills are often available on the provider’s website or app. Some travel SIMs allow auto-refills for seamless use.

You can activate a travel SIM card by simply inserting it into the SIM card tray in your phone. Follow the setup instructions on-screen, which may involve entering a PIN. Restart your device if prompted, and ensure your device connects to the network. 

You can buy travel SIM cards in advance online or at airports. Typically, you can purchase a local SIM once you arrive at your destination country, whereas you can get international SIMs online.

International SIM cards can be purchased online through global providers, at airports, or from travel agencies specializing in connectivity solutions.

You can get a local SIM card at the airport when you arrive at your destination. Or, purchase one from convenience stores or official carrier shops in major cities. Ensure your passport is handy, as you might need ID for purchase.

Avoid unexpected charges with your travel SIM card by disabling auto-refill or extra credit options as necessary. Then, make sure to monitor your usage through the carrier’s app. Some carriers allow you to set data limits on your phone, preventing overuse. When you get home, make sure you deactivate the SIM and turn off roaming.

Local SIM cards often expire within 30-90 days of inactivity. International SIM cards may remain active for months, but the exact duration depends on the provider. Check the terms to avoid losing credit or service.

Travel SIMs are often more cost-effective and simpler for solo travelers, while portable WiFi devices are ideal for groups, as they can connect multiple devices simultaneously. However, WiFi devices require charging and often have rental fees and potential penalties for loss or damage.
