One eSIM can cover Singapore and Bali. Our Asia 7 eSIM gives you 10 GB to share across both destinations for $23.99, valid for 30 days. If you can split your data evenly, our separate 5 GB Singapore and Indonesia plans total $20.98. Each lasts 30 days, saving you $3.01 against the shared pack.
We sell the Travelsim Asia plans in this guide. Asia 7 is convenient when you want one installation and a balance you can use at either stop. Separate plans can cost less, and Airalo has lower regional prices than ours at 5 GB and 20 GB. The right choice depends on your data budget and how much of the trip you spend in each destination.
Which Travelsim Asia pack covers Singapore and Bali?
Bali is in Indonesia, so the plan must include both Singapore and Indonesia. Asia 7 covers both. It also includes Cambodia, Malaysia, the Philippines, Thailand and Vietnam if your itinerary grows.
Asia 14 includes Indonesia but excludes Singapore. Our Malaysia–Thailand–Singapore pack includes Singapore but excludes Indonesia. Asia 12 covers both, but its 10 GB / 30-day plan costs $42.99 compared with $23.99 for Asia 7. A larger destination count does not make it the better choice for this route.
Use the regional coverage guide if you are adding other stops.
One shared plan or two country plans?
| Total data | Asia 7, shared | Two country plans | Saving with separate plans |
|---|---|---|---|
| 10 GB across the trip | $23.99 | 5 GB Singapore $9.99 + 5 GB Indonesia $10.99 = $20.98 | $3.01 |
| 20 GB across the trip | $40.99 | 10 GB Singapore $12.99 + 10 GB Indonesia $16.99 = $29.98 | $11.01 |
Every plan in this table has 30-day validity. Asia 7 starts on first connection in a covered destination and keeps the same expiry as you travel. The country plans start separately when they connect in their respective destinations.
Equal total data does not mean the allowances work the same way. On a shared 10 GB pack, you could use 2 GB in Singapore and 8 GB in Bali. With two 5 GB country plans, unused Singapore data cannot move to Indonesia. Compare the split you expect to use, not just the total.
For a short Singapore stay followed by more time in Bali, our 1 GB Singapore plan costs $2.99 for seven days. Pair it with 10 GB Indonesia for $16.99 over 30 days and the total is $19.98. That buys 11 GB with separate balances and different validity periods; it is not a like-for-like shared 10 GB offer.
If you are only changing planes in Singapore and do not need mobile data there, an Indonesia-only plan may be enough. You do not need regional coverage simply because your flight connects through Singapore.
Regional fixed-data plans compared
| Regional product | 5 GB / 30 days | 10 GB / 30 days | Larger pack / 30 days |
|---|---|---|---|
| Travelsim Asia 7 | $17.99 | $23.99 | 20 GB: $40.99 |
| Airalo Asia | $15.00 | $25.00 | 20 GB: $39.00 |
| Ubigi Best Asia | Not listed | $28.00 | 25 GB: $44.00 |
| Ubigi Asia | Not listed | $42.00 | Not listed |
| Saily Asia and Oceania | $19.49 | $35.99 | Not listed |
All products in this table include Singapore and Indonesia. These are one-off plans, not monthly subscriptions. “Not listed” means no matching allowance and validity in the captured offers; it does not mean the provider has no other sizes. Ubigi’s 25 GB pack contains more data than the 20 GB packs.
For 5 GB, Airalo costs $15.00 against our $17.99. At 10 GB, our $23.99 Asia 7 plan costs less than Airalo at $25.00, Ubigi Best Asia at $28.00 and Saily at $35.99. At 20 GB, Airalo costs $39.00 against our $40.99. There is no single cheapest provider at every allowance.
For a small shared allowance, Asia 7 also offers 1 GB / seven days for $5.99 and 3 GB / 15 days for $11.99. Ubigi Best Asia has 3 GB / 30 days for $12.00, just one cent more with longer validity. Saily’s 3 GB / 30-day plan costs $12.49.
When an unlimited plan is worth comparing
For frequent video uploads or laptop use, compare the full cost of a fixed pack and top-ups with an unlimited plan. Unlimited does not mean full-speed data for the whole trip.
| Regional product | 15 days | 30 days | Full-speed and sharing limits |
|---|---|---|---|
| Ubigi Best Asia | $45.00 | $66.00 | 30 GB across the 15-day plan or 60 GB across the 30-day plan, then 2 Mbps. |
| Airalo Asia | $49.00 | $73.50 | Default 3 GB per 24 hours, then 1 Mbps until reset; check the selected package for exceptions. |
| Holafly Asia | $51.50 | $76.50 | No numerical full-speed threshold stated for Asia; operator fair-use restrictions apply. Hotspot: 1 GB/day. |
| Saily Asia and Oceania | $54.99 | $86.99 | 5 GB/day, then up to 1 Mbps. Unlimited terms restrict high-volume computer tethering. |
Ubigi Best Asia has the lowest 15- and 30-day unlimited prices among these four products. Its allowance runs across the whole trip; Airalo and Saily use daily allowances. Holafly also offers exactly 14 days for $48.90, though Ubigi’s 15-day plan still costs less at $45.00. Airalo and Ubigi allow hotspot sharing, which uses their stated data allowances.
Check the networks for this regional pack
| Regional product | Singapore | Indonesia, including Bali |
|---|---|---|
| Travelsim Asia 7 | M1 and Singtel, 4G | Telkomsel, listed 5G access |
| Airalo Asia | StarHub and Singtel | Telkomsel |
| Ubigi Best Asia | Simba and StarHub | Indosat Ooredoo Hutchison |
| Holafly Asia | Singtel | XL and Telkomsel |
| Saily Asia and Oceania | Not named on the regional page | Not named on the regional page |
A network listing describes the plan’s available partners, not a guarantee of signal at every beach, hotel or viewpoint. A 5G listing also depends on your device and location. Our Indonesia-only plan lists Telkomsel, Indosat, XL and Smartfren; Asia 7 lists Telkomsel in Indonesia. Do not assume two products from the same provider use identical networks.
For the Bali part of your trip, see our Bali eSIM guide. For a Singapore-only comparison, use the Singapore buyer’s guide.
Install once and keep the same balance
For Asia 7, you need an unlocked, eSIM-compatible phone. Install over Wi-Fi using the link or QR code in your email. No app or account is required. Select the travel eSIM for mobile data and enable data roaming on that line when you are ready to connect.
Validity starts on the first connection in a covered destination, not at purchase or installation. If you connect in Singapore first, the clock starts there. Flying to Bali does not restart it. If you live in Singapore, leave the travel line disabled until you want the plan to begin.
Keep the eSIM installed when you arrive in the next country. It uses a supported local network and the same remaining allowance. You can check the balance and available top-ups from the dashboard linked in your email. Review the top-up’s price and validity before buying; adding data does not automatically add new destinations.
Asia 7 is data-only, without a local phone number or standard calls and SMS. The installation guide explains the setup. For allowance planning, the multi-country data guide helps you budget across the full trip.
Choose for your two stops
Choose our Asia 7 eSIM when one installation and a flexible shared balance matter to you. At 10 GB / 30 days, it costs $23.99. Choose separate Singapore and Indonesia plans when their savings and individual allowances fit your itinerary. If you prefer a regional 5 GB or 20 GB pack, Airalo has the lower price in this comparison.
