Saily’s Europe eSIM covers 35 countries and includes unlimited hotspot sharing, and its Unlimited plan costs US$49.99 for 7 to 30 days with a daily full-speed allowance. Our Global eSIM gives unlimited data across 165+ countries, from USD 9.99 for 3 days, under a daily high-speed allowance.
You buy “unlimited” for Europe and find the fast part ends before the day does.
Saily’s Unlimited Europe plan gives 5 GB a day at full speed
Saily’s Unlimited Europe plan gives 5 GB a day at full 4G/5G speed. Once you use it, you stay online at up to 1 Mbps for the rest of that day (Saily, 2026).
Saily’s terms say the allowance runs for each 24-hour period, from 00:00 to 00:00 local midnight in your current time zone. Full speed resumes at the next reset. Saily’s terms also say the allocation is either 3 GB or 5 GB depending on the destination country, as specified in the offering.
Validity depends on the plan you pick. Saily publishes unlimited options of 5, 7, 10, 15, 20, 25 or 30 days (Saily, 2026). Hotspot sharing is unlimited on Saily’s own terms, so the whole group can tether to one plan.
How much does a Saily Europe eSIM cost, by plan?
Validity runs on the data plan. Saily says the eSIM itself won’t expire, but once you activate a plan it must be used within its window. Regional plans carry 7, 15, 30, 90, 180 or 365 days (Saily, 2026). When the window closes, you buy another plan to get online.
Which extras come with a Saily Europe eSIM besides mobile data?
Hotspot sharing comes with all of Saily’s plans, and Saily calls it unlimited. Calls and texts are extras: Saily offers an eSIM with a phone number, with a minutes plan for calls and a text message plan for SMS (Saily, 2026).
Call minutes cover both incoming and outgoing calls. Data-only plans carry no local number, so Saily points to VoIP apps like WhatsApp, FaceTime and Facebook Messenger for calls.
Saily also lists web protection and ad blocking among its security features, and says its support team chats around the clock. Pick the extras before you pay, since a data-only plan stays data-only.
How do you install and start a Saily eSIM for Europe?
Download the Saily app, pick a plan, install the eSIM, then turn on the eSIM and data roaming. Saily recommends installing before you leave for Europe (Saily, 2026).
Saily says delivery is instant. Buy on the website and a QR code arrives by email; buy in the app and the plan shows on your profile. Saily says the plan then activates automatically when you reach the first country in it.
On most devices that automatic start depends on two switches: the Saily eSIM itself and data roaming. Flip both and you’re set before you land.
Which terms should you read on a Europe eSIM before paying?
Read the country count, the phone-number terms, the start trigger and the device rule. Saily’s Europe plan covers 35 countries, and Saily adds that coverage quality depends on local network providers (Saily, 2026).
Data-only plans carry no local phone number, so there are no calls or texts from the plan itself. Your regional plan activates when you arrive in the first country included, provided your Saily eSIM is on and roaming is enabled. Your device must be eSIM compatible; Saily says most smartphones and tablets made after 2019 are, but devices bought in countries with eSIM restrictions, such as mainland China, may not support eSIMs.
Setup is where buyers at rival companies report trouble. A one-star Trustpilot review of aloSIM from August 13, 2026, by Osman D., reads:
“No Russian manuals available. I purchased aloSIM for my family while they were traveling, but none of them could set up the eSIM. As an experienced Windows and Android user, I could have probably figured it out by trial and error, but my family couldn’t. It’s way too complicated with English-only instructions. Plus, after my payment successfully processed, the app still asked me to buy the plan again. # update since you are planning to add Russian instructions, I’ll give aloSIM another try. My family is heading to Turkey at the end of August, and if everything goes well, I’ll update my review to 5 stars.”
Check the instructions before you fly. Then land and go.
Where does Saily’s Europe eSIM stop, and what covers the rest of your trip?
Saily’s Europe eSIM stops at its list of 35 countries, from Austria to the United Kingdom (Saily, 2026). Past that list you need another plan.
Saily says it offers mobile data plans in 200+ destinations, and that you install your eSIM once and add new plans for future trips. Its table row shows 12 countries in the Latin America plan, a Global plan covering 121 countries, and plans per country such as Mexico and Japan.
A Europe trip that continues past the list means a second purchase. Plan the whole route before you pick the plan.
What does ‘unlimited’ include on a travel eSIM for a Europe trip?
Each company publishes its own daily full-speed allowance and the speed after it. Saily’s Unlimited plan gives 5 GB a day at full speed, while the others’ terms set theirs differently. Avid and business travelers weigh the allowance and the country list against how much they use in a day.
The reset clock differs too. Airalo says its daily allowance resets every 24 hours counted from the time you activated your eSIM, while Saily ties its reset to local midnight (Airalo, 2026; Saily, 2026). Airalo’s threshold is 3 GB a day, then 1 Mbps. Ubigi publishes 60 GB of full speed, then 2 Mbps. Holafly says some network operators may temporarily reduce your speed after a certain amount of high-speed data.

In the table, the Airalo, Holafly, Saily and Ubigi cells use each company’s own published wording or a brief summary of it, while the Maya Mobile cells give our own terms.
Speed is what buyers argue about. A one-star Trustpilot review of Ubigi from October 7, 2026, by a reviewer who gave no name, reads:
“Speeds are horrendous and times out 9 out of 10 times in multiple countries even though I purchased not regional but individual country plans to avoid the lag.”
How Maya keeps one eSIM on your phone for Europe and every trip after
A Europe trip is one stretch of a longer map, and a regional plan ends at its country list. Our Global eSIM covers 165+ countries with one plan, so there’s no plan to add per country.
Land, connect, go.
FAQ
Which countries does Saily’s Europe eSIM cover?
Saily’s Europe eSIM covers 35 countries. Saily lists Austria, Belgium, Bulgaria, Croatia, Cyprus, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Gibraltar, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Liechtenstein, Lithuania and Luxembourg. It also lists Malta, the Netherlands, Norway, Poland, Portugal, Romania, San Marino, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom (Saily, 2026).
How do roaming charges work when I use a travel eSIM in Europe?
Saily says that with a Europe eSIM plan you avoid sky-high roaming fees by enabling international roaming on the eSIM. Saily’s setup steps tell you to enable data roaming for your Saily plan. Saily also advises disabling your personal SIM card to prevent unexpected roaming charges from your home provider (Saily, 2026).
Can I add more days if my Europe trip runs long?
Yes. Buy another plan from the Maya app, anytime, or at maya.net. For each trip you only buy a new plan, with no reinstalling. Auto Top-Up is optional and off by default; if you turn it on, it automatically buys the same plan again when the current one expires.
Which phones work with a Saily Europe eSIM?
Any eSIM-compatible phone works. Saily says most smartphones and tablets made after 2019 support eSIM, but a device bought in a country with eSIM restrictions, such as mainland China, may not. Saily’s terms add that your device must be unlocked and eSIM-compatible (Saily, 2026).
How long can a Saily Europe eSIM sit unused before the plan starts?
Saily’s support page says you can install and activate the eSIM within 30 days of purchase. The plan starts automatically when you arrive in the first country included, as long as your Saily eSIM is on and roaming is enabled (Saily, 2026).
What should I do if my eSIM shows no signal when I land in Europe?
Open your phone settings and make sure the Maya eSIM is turned on and chosen for Cellular Data. If you installed it before arriving, set it as the primary Cellular/Mobile Data plan. If that doesn’t fix it, you may be in an area without service, or there may be a network issue outside our control; wait and check later.
Maya gives you one eSIM with unlimited data across 165+ countries, installed once and ready for every trip, from USD 9.99 for 3 days.
