Will my home phone number receive calls while I use the eSIM?
Yes - if your home SIM stays installed and active, calls and SMS to your home number arrive normally. The eSIM only handles data; voice service stays on your home line. Just remember that incoming calls and texts to your home number while abroad may trigger roaming charges from your home carrier.
Which eSIM is best for travelling to Portugal-voice?
eSIMno is an excellent option for travelers heading to Portugal-voice. We offer a diverse range of eSIM plans - including regional, local, and lifetime options - with reliable coverage on local networks.
Can I install my eSIM before traveling?
Yes - setting it up before your trip is the easiest approach. Your confirmation email contains the QR code, a one-tap install link and the manual SM-DP+ / activation codes (the same options are also available via sign in > Profile > My eSIMs > Install). While on Wi-Fi at home, install it with the one-tap link on your phone, or - to use the QR - show it on another screen or a printout and scan it with the phone you are setting up (not another phone). Installing 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 its Data Roaming off until you are ready to start - if your plan covers the country you are in right now, turning the line on connects and starts the countdown immediately, even if you do not browse anything. Please note: once installed, an eSIM is considered used and is no longer eligible for a refund.
What data plans are available for the Portugal-voice 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.
Is the eSIM connection secure?
eSIM connections are as secure as standard cellular connections - encrypted by the carrier network. For added security on public networks (cafes, airports), use a VPN. The eSIM profile itself is digitally signed and can't be cloned like a physical 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 share data from my eSIM with someone else's phone?
Yes, through Personal Hotspot. Activate hotspot on your phone, share the password, and the other device connects to your data. Data used by connected devices counts toward your eSIM plan, so monitor usage to avoid running out faster than expected.
What should I do if I see a 'No network' message after activating my eSIM?
If you see a 'No network' message after activation, try these steps in order: (1) Toggle airplane mode on for 10 seconds, then off. (2) Confirm data roaming is enabled for the eSIM line. (3) Manually select a network in cellular settings. (4) Restart your phone. If the issue continues, contact eSIMno support via WhatsApp or email.
Are there any hidden fees or extra charges?
No. The price you see at checkout is the total price - no activation fees, no hidden taxes, no roaming surcharges. Your data plan is fixed-price, and you'll never receive a surprise bill from your home carrier as long as you keep cellular data off on your home SIM.
How do I set up the eSIM on my device?
The fastest way is straight from your order confirmation email, which now contains - for each eSIM - the QR code, a one-tap install link, and the SM-DP+ / activation codes. On the phone you'll use, tap the one-tap install link; or, to use the QR, show it on another screen or a printout and scan it with that same phone (not another phone); or enter the codes manually. The email also has an "Install eSIM" button that opens your eSIM's detail page and launches the install pop-up (sign in if prompted), and you can reach the same pop-up anytime via Profile > My eSIMs > find your plan (shown as "Ready to install") > Install. After installing, turn Data Roaming ON for your eSIMno line (iPhone: Settings > Cellular; Android: Settings > Connections/Network) - without it the eSIM installs but shows no internet.

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.
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.
