Stay Connected in Southeast Asia with an eSIM: Instant Data, Zero Drama
The first time we tried to buy a SIM card in Bali, it felt like stepping into a government office disguised as a phone shop. We took a number, sat on a row of plastic chairs, and waited while clerks processed each customer with the momentum of a soap opera plot twist … dragged out, dramatic, and never in a hurry.
By the time the screen clicked from 067 to 068, Cary was already deep in conversation with an Australian couple sitting next to us. The couple said they’d signed up for a yoga class in Ubud thinking it would be gentle stretching. Instead, they ended up in a group sound healing where everyone was told to scream into the jungle.
“I never thought primal yelling would fix my marriage,” the wife said with a grin, “ but it did loosen my jaw tension.”
Cary chuckled, “So you paid to do what my neighbors back home get the cops called on for free.”
The whole row laughed.
That had just been Bali. In Penang we ducked into the only shop without a line. We thought we’d dodged the queue, but the paperwork ceremony was alive and well. Passports shuffled, forms in triplicate, the whole bit. And if it happened in Bali and Penang, you could bet versions of it were alive and well across Southeast Asia.
Later, we skipped the whole circus. No lines, no kiosks, and best of all, no wrestling with a paperclip in the back of a taxi just to pop open a SIM tray. We set up the eSIM before boarding, so by the time we landed in Bali and were standing on the curb, I already had the Grab app open, driver ordered, WhatsApp ready, and a reliable internet connection that did not sputter or lock me into one useless app. SCORE!
Why eSIMs Beat the Airport Shuffle
For those new to the idea, an eSIM is a digital SIM. You bought it online, followed the guide, and it installed instantly. Then, voilà … you were online.
For slow travelers, a Southeast Asia eSIM means no more chasing kiosks at the airport after a red-eye flight. It also means you can compare plans calmly, with your glasses on, instead of nodding to whatever bundle a salesperson waved at you.
The Southeast Asia eSIM Landscape
Here’s where things get interesting. Not all eSIMs are equal. Some cover more countries, some include perks like VPNs or flight lounge access, and some work better for long stays.
We dig through the top options, and here’s what stands out (prices checked in September 2025)
Airalo
It is reliable. We used this for a month in Bali. It never hiccupped, even when Mitha streamed a Korean drama during a tropical downpour that knocked the power out on half the street. Their 90-day, 50 GB plan at $100 was popular with long-term travelers.
Saily
At first glance, Saily looked pricey. Then we noticed it came with a built-in VPN and ad blocker. Cary called it “the only plan that cares about my browsing privacy and my sanity.” Their 90-day plan work out to less than two bucks a gigabyte, which felt like winning.
Simify
Simify is the plan for people who could not resist Netflix binges, even in paradise. Unlimited data for about ninety dollars meant you could finish an entire series while your laundry spun endlessly at the corner shop. It also offered 10 GB plans and unlimited data for around $100 for 60 days.
Jetpac
A quirky one. Jetpac threws in airport lounge access with some of its plans. Cary was thrilled until he realized “free lounge” just meant “extra pretzels and a plug socket.”
Roamless
It is the global option, working in over 200 countries, including all of Southeast Asia. Expensive per GB, but the joy of never swapping plans again was worth it if your trip looked more like a border-hopping buffet.
Their “RoamlessFlex” pay-as-you-go plan never expired, so you only paid for what you used. They also offered regional and country bundles if you preferred fixed plans.
Which One Worked for Slow Travelers?
Airalo and Saily are the dependable types, equally happy to tag along on a manic border-hop or sit quietly in your pocket for six months while you pretend to “live like a local.” They are simple, sturdy, and just dull enough that you almost forget they are there, which, for data plans, is high praise.
For travelers who burn through data like it is breakfast coffee, Simify is the winner. The plans cost more, but unlimited data and solid global coverage make it the go-to for digital nomads, remote workers, or anyone glued to their screen. Setup is painless, instant activation, no sneaky fees, just peace of mind for the long haul.
Jetpac is the wildcard for anyone who loves a freebie. Of course, if you already carry a credit card that gets you into lounges for free, that perk loses some shine.
If your trip looks more like an all-you-can-eat world buffet, Roamless is for you. It is pricier per GB, but the ease of one eSIM that works everywhere is worth it if border-hopping is your style. It is one eSIM, 200 countries, automatic switching. It is like carrying a universal remote for the internet. The RoamlessFlex wallet lets you pay as you go, and the credits never expire, which feels almost unpatriotic for a telecom.
No Tears, No Drama, Just Data
Cary and I were not afraid of tech. We both handled apps and gadgets just fine, which was why we expected setting up an eSIM to involve at least three error messages and one frantic Google search. Instead, last month in Kuala Lumpur we were connected before the bags even hit the carousel. Cary looked at me and said, “That was it? No drama? Almost disappointing.”
Travel in Southeast Asia tests your patience: scooters buzz past like mosquitoes, traffic that Google Maps swears will take 15 minutes somehow turns into an hour, and sudden downpours soak you before you can open an umbrella. Reliable data makes all of that easier to handle.
If you are planning Bali or a longer Southeast Asia trip, do yourself a favor and set up an eSIM before you fly. It saves you the long wait at the mobile provider office, the paperwork shuffle, and the awkward “do I really need the premium tourist bundle?” conversation. Pick a plan that fits your style, and by the time you land you are already scrolling ride-hailing apps to look for a driver instead of sweating in line to buy a SIM card.
Pro Tips
Set it up before you flew. Install your eSIM at home while your Wi-Fi is still strong. Doing it in Bali arrivals with jet lag was like trying to thread a needle on a roller coaster.
Get the app. Most providers (Airalo, Saily, Simify) have apps that showed your data balance.
Cary checked ours like it was the stock market and announced, “We are down to 3 GB—sell, sell, sell.”Buy more than you need. Grab rides, Google Maps detours, and sending photos of mie goreng to your friends back home chew through data. A little extra isn’t waste, it’s peace of mind. Or, as Cary says, “Insurance against another YouTube rabbit hole.”
Indonesia gave you 90 days of free use on a foreign-bought phone. After that, your Indonesian SIM will stop working. If you want to use your foreign-bought phone in Indonesia using Indonesia’s SIM for more than 90 days, you have to register your phone and pay the tax if your phone worth more than USD 500.

Now instead of staring at a red LED screen in a Telkomsel office, I was already in a café in Ubud arguing with Cary about whether roosters counted as background noise on a video call. eSIMs could not solve Bali traffic, but it eliable internet before your luggage even showed up.
For us, an eSIM is not just tech, it is the freedom to start our trip the moment we landed, not three hours in a phone shop queue. For slow travelers, that is priceless.
Ready to skip the kiosk shuffle? Set up your eSIM before your next trip, pour yourself a coffee, and land in Southeast Asia already connected. Your future, less-frustrated self will thank you.
