A honeymoon is a good time to be a little less connected, but most couples still want working phones. You will want to message your driver when you land, find the trattoria you bookmarked, share a sunset photo with family and look up the ferry schedule when plans shift. Relying on hotel Wi-Fi alone can leave you stranded in the moments you need data most, such as arriving at an airport or getting lost on a mountain road.
For years, the options were expensive carrier roaming or hunting for a local SIM card at the airport. Today, most recent smartphones support eSIM, a digital SIM that you can download and install before you leave home. A travel eSIM can give you data in your destination as soon as you land, often for less than daily roaming charges, while your usual number stays available for calls and texts.
This guide explains how eSIMs work, how they compare with roaming, how to check whether your phone is compatible, how to install one and how much data you might need. It ends with practical tips for staying connected in remote honeymoon spots, plus a gentle reminder to put the phone down once in a while.
What Is an eSIM?
An eSIM is a SIM card built into your phone. Instead of inserting a physical card, you download a mobile plan, called an eSIM profile, usually by scanning a QR code or tapping a button in a provider's app. Many phones can store several eSIM profiles and keep two lines active at once, which means you can keep your home number on while using a travel eSIM for data.
Travel eSIMs are typically data-only plans sold for a specific country, a region such as Europe or Southeast Asia, or a wider set of countries. You choose an amount of data and a validity period, such as a week or a month. Providers such as Airalo, Saily, Yesim and GigSky offer plans for many destinations. Some companies, including Drimsim, also offer physical travel SIM cards for phones that do not support eSIM.
eSIM vs. Roaming vs. Local SIM
Each approach has its place.
- Carrier roaming: The simplest option. Your US plan may offer an international day pass or include some international data. It works automatically, keeps your number for calls and texts and needs no setup. Daily passes can become expensive over a longer trip. Some plans also slow speeds abroad.
- Travel eSIM: Usually cheaper than daily roaming for trips longer than a few days. Quick to set up and can be installed before departure. Most are data-only, so you use messaging and calling apps over data.
- Local physical SIM: Can offer good value and a local number. It often means finding a shop on arrival, presenting identification in some countries and swapping cards in and out of your phone.
For most honeymoons, a travel eSIM offers a good balance of cost and convenience. Compare current prices for your trip, since carrier plans and eSIM rates change often.
Is Your Phone Ready?
Before buying an eSIM, check two things. First, your phone must support eSIM. Most recent iPhones, Google Pixels and Samsung Galaxy flagships do, but not every model or regional version does. Check your phone settings or the manufacturer's website. Second, your phone must be carrier-unlocked. Phones bought outright are often unlocked, while financed phones may be locked until paid off. Your carrier can tell you your phone's status and may unlock it if it meets their requirements.
It is also worth checking that your phone can keep two lines active at once. That allows you to receive texts, including security codes from your bank, on your home number while using the eSIM for data.
How to Install a Travel eSIM
Installation usually takes just a few minutes. A typical process looks like this:
- Choose a plan for your destination and duration, then buy it through the provider's app or website.
- Install the eSIM while connected to Wi-Fi, ideally a day or two before departure, by scanning the QR code or following the in-app steps.
- Label the new line clearly, for example "Travel," so you can tell it apart from your home line.
- Set the travel eSIM as your line for cellular data. Keep your home line for calls and texts if you want them.
- Turn off data roaming on your home line to avoid unexpected charges. Turn on data roaming for the travel eSIM if the provider instructs you to.
- On arrival, switch off airplane mode and wait for the eSIM to connect to a local network.
Check when your plan's validity starts. Some begin when you install, others when you first connect in the destination. Do not delete the eSIM until your trip is over, as many profiles cannot be reinstalled.
How Much Data Do You Need?
Usage varies widely, so these are approximate guidelines. For light use, such as maps, messaging and occasional browsing, a few gigabytes per week may be plenty, especially if your hotel has good Wi-Fi. For heavier use, including frequent photo uploads, video calls, social media and streaming, you may want 10 GB or more for a week, or an unlimited plan where offered.
Many providers let you top up if you run low, so it can make sense to start with a moderate plan and add data as needed. To stretch your data, download offline maps and playlists before you go, set photo backups to Wi-Fi only and turn off automatic app updates while traveling.
Calls, Texts and Two-Factor Codes
Because most travel eSIMs are data-only, you will typically use apps such as WhatsApp, FaceTime, iMessage or Signal to stay in touch. WhatsApp is very widely used for communicating with drivers, guides and hotels in many countries, so it is worth installing before you leave.
Keep your home line active if you need to receive text messages for security codes from banks or other services. Receiving texts while roaming may be free or low-cost depending on your plan, but check your carrier's rates. Calls on your home line while abroad may be charged at roaming rates, so check your carrier's policy before answering.
Remote Destinations and Multi-Country Trips
Coverage varies by destination. On private islands in the Maldives or French Polynesia, resorts usually provide Wi-Fi, but cellular coverage at sea or on outer islands can be patchy. Safari camps in the Serengeti or the Sabi Sand may offer limited Wi-Fi in common areas. Coverage in the bush can be intermittent. Parts of Lapland, Iceland and Southern Utah can also have dead zones.
If your trip spans several countries, such as Greece and Italy or Tanzania and Zanzibar, check whether a regional plan covers every stop. Regional plans can be more convenient than buying one per country. For destinations with limited coverage, download offline maps and keep important confirmations available offline.
Tips for a Connected but Present Honeymoon
A few small habits can help you stay connected without letting your phones take over:
- Save hotel addresses, transfer details and emergency contacts offline.
- Share your itinerary with a trusted family member.
- Pack a compact power bank and the right travel adapter.
- Agree on phone-free times, such as dinners or sunsets.
- Turn on Wi-Fi calling on your home line where your carrier supports it.
The goal is to make your phone a helpful tool rather than a distraction, so you can focus on each other.
Frequently asked questions
Can we keep our US phone numbers while using an eSIM?
Yes, in most cases. Many phones can keep two lines active, so you can use the travel eSIM for data and keep your home line on for calls and texts. Turn off data roaming on your home line to avoid charges. Check your carrier's rates for calls and texts abroad.
When should we install our travel eSIM?
Many travelers install it a day or two before departure while on reliable Wi-Fi, then activate or switch to it on arrival. Check your provider's instructions, since some plans start their validity period when installed and others when they first connect in the destination.
Do travel eSIMs work in the Maldives or on safari?
Plans are available for many destinations, including the Maldives and Tanzania, but coverage depends on local networks. Resorts and lodges usually offer Wi-Fi, while coverage at sea, on remote islands or in the bush can be intermittent. Check the provider's coverage details for your destination.
Is an eSIM cheaper than an international day pass?
For longer trips, often yes. Daily passes from carriers can add up over a week or two, while travel eSIMs typically charge for a set amount of data. For very short trips, a carrier pass may be simpler. Compare current rates for your exact trip length.
What if our phone does not support eSIM?
You can use your carrier's roaming options, buy a local physical SIM card on arrival, or use a physical travel SIM from a provider such as Drimsim. Make sure your phone is unlocked if you plan to use a SIM from another provider.
Can one eSIM cover several countries?
Yes. Many providers sell regional plans, such as Europe or Asia, or global plans for many countries. These can be convenient for multi-stop honeymoons. Check that every country on your route is included, along with data allowance and validity.
