Will I get notifications when my data is running low?
Yes. eSIMno sends email and push notifications when you've used 50%, 80%, and 100% of your data allowance. You can also check usage anytime in the eSIMno Center or in your phone's cellular settings to track consumption in real time.
Can I use the eSIM right after purchase or do I need to wait?
Yes - you can install it immediately after purchase. Your order email arrives within minutes and contains the QR code, a one-tap install link and the manual codes, plus an "Install eSIM" button; you can also sign in > My eSIMs > Install any time. Installing right away does not start your plan - the validity countdown only begins when the eSIM connects to a mobile network inside your plan's coverage area. Keep the eSIM line and Data Roaming off until you are ready to start; if your plan covers the country you are in right now, turning the line on starts the countdown immediately.
Will the eSIM affect my phone's battery life?
Running two SIM lines (physical + eSIM) uses slightly more battery than one, since the phone monitors both networks. The difference is usually 5-10% over a full day. To minimize impact, disable the line you're not actively using or turn off cellular data on the inactive line.
Does the eSIM work in rural areas and small towns?
Coverage depends on the partner network's reach in Ireland-unlimited. Major cities, tourist areas, and highways typically have strong 4G/5G coverage. Remote rural areas may have weaker signal or fall back to 3G. Download offline maps before heading off the beaten path.
Can I use my SIM card and eSIM at the same time?
Yes. On dual-SIM devices (most modern iPhones and Android phones), you can run your physical SIM and the eSIM simultaneously. Use your home SIM for calls and SMS, and the eSIM for mobile data. Keep in mind that leaving your home SIM active may trigger roaming charges if you use it for calls or texts abroad.
What data plans are available for the Ireland-unlimited eSIM?
eSIMno provides various data plans ranging from 1 GB to unlimited data, with options from 7 days to 90 days of service. Plans also include regional and lifetime options for travelers who want flexibility across multiple destinations.
Can I make phone calls or send SMS?
eSIMno is a data-only service, so you can't make traditional voice calls or send SMS through the eSIM line. However, you can use messaging and calling apps over data - WhatsApp, iMessage, FaceTime, Telegram, Signal, and Google Meet all work normally.
Can I use the eSIM for my smartwatch?
Some smartwatches (Apple Watch Cellular, Samsung Galaxy Watch LTE) support eSIM, but they typically require a plan from your home carrier rather than a travel eSIM. eSIMno plans are designed for phones and tablets - check device compatibility before purchase if you intend to use a wearable.
What makes eSIMno different from other eSIM services?
eSIMno partners directly with local operators in over 200 countries, eliminating intermediaries. This direct relationship lets us offer competitive pricing, extensive coverage, and faster activation than resellers who route data through third parties.
Should I enable data roaming for the eSIM?
Yes - you must enable data roaming for the eSIM line, even though there are no roaming charges. The eSIM connects to a local partner network and your phone treats this as roaming. Enable it: iPhone > Settings > Cellular > eSIMno line > Data Roaming ON; Android > Settings > Network > SIMs > eSIMno > Roaming ON. This setting only affects the eSIM, not your home SIM.
Can I extend my eSIM plan validity?
The validity of a package that is already running cannot be extended, but you can top up: a top-up adds a new package with its own data AND its own validity days. Packages run one at a time - the top-up waits in queue and activates automatically when your current package ends (data used up or days expired), and its own days start counting from that moment. In practice this keeps you connected longer, even though the current package's own end date does not move.
Can I keep my WhatsApp number while using an eSIM?
Yes. Your WhatsApp number stays linked to your home SIM, so all your chats, contacts, and groups remain unchanged. WhatsApp uses data (not the SIM line directly) for messages and calls, so it works seamlessly over your eSIMno data.
