This article is a like-for-like price check of Asia travel eSIMs from two stores: Global Starlink (our own) and SimCorner. We read the prices from each store's own website on 11 November 2026. All figures are list prices in Australian dollars, as shown before checkout. Prices change, so please check both websites before you buy.
We sell eSIMs, so we have an interest in the result. Every data size is shown, including rows where SimCorner costs less or lasts longer.
How to read the tables
Each row pairs plans of the same data size, showing validity then price; "None" means no plan of that size. SimCorner's fixed-data plans mostly run for 30 days, while several of ours run for 3, 7 or 15 days, so every row shows both validities and all the lengths we sell. SimCorner has two data-only lines per country, a fixed-data "Data eSIM" and an "Unlimited eSIM"; both are in the tables.
Japan eSIM prices
SimCorner names KDDI and SoftBank as its Japan networks. Our Japan eSIM runs on IIJmio. Our plans are in the Japan eSIM collection.
| Data | SimCorner | Global Starlink |
|---|---|---|
| 1GB | 7 days, A$5.00 | None |
| 3GB | 30 days, A$12.00 | None |
| 5GB | 30 days, A$18.00 | 3 days, A$7.90; 7 days, A$9.90 |
| 10GB | 30 days, A$25.00 | 7 days, A$13.90; 15 days, A$15.90 |
| 20GB | 30 days, A$35.00 | 7 days, A$22.90; 15 days, A$24.90; 30 days, A$29.90 |
| 30GB | 30 days, A$52.00 | 7 days, A$33.90; 15 days, A$34.90; 30 days, A$39.90 |
| 50GB | None | 15 days, A$49.90; 30 days, A$59.90 |
| Unlimited | 4 days, A$24.00; 7 days, A$37.00; 10 days, A$47.00; 15 days, A$67.00; 31 days, A$107.00 | None |
Our 5GB and 10GB plans have a lower ticket price, but they last 15 days at most against SimCorner's 30. Divide price by days and SimCorner's 5GB and 10GB plans cost less per day.
China eSIM prices
SimCorner names China Unicom and China Telecom. Our mainland China eSIM connects to China Unicom, China Telecom or China Mobile. Our plans are in the China eSIM collection.
| Data | SimCorner | Global Starlink |
|---|---|---|
| 1GB | 7 days, A$5.00 | None |
| 3GB | 30 days, A$9.50 | None |
| 5GB | 30 days, A$14.00 | None |
| 10GB | 30 days, A$20.00 | 3 days, A$12.90; 7 days, A$14.90; 15 days, A$16.90; 30 days, A$17.90 |
| 20GB | 30 days, A$40.00 | 7 days, A$16.90; 15 days, A$21.90; 30 days, A$29.90 |
| 30GB | 30 days, A$63.00 | 7 days, A$26.90; 15 days, A$29.90; 30 days, A$39.90 |
| 50GB | None | 15 days, A$54.90; 30 days, A$59.90 |
| Unlimited | 5 days, A$25.00; 8 days, A$35.00; 16 days, A$69.00; 22 days, A$95.00; 30 days, A$99.00 | None |
The 10GB row is close: A$20.00 at SimCorner and A$17.90 with us, both for 30 days. Our smallest China plan is 10GB, so anyone needing only 3GB or 5GB pays less at SimCorner. The gap widens at 20GB and 30GB.
Thailand eSIM prices
SimCorner names AIS and TrueMove H. Our Thailand eSIM runs on TrueMove H or DTAC, depending on the option, and does not use AIS. Our five options do not match SimCorner's sizes, so this table lists each store's plans in order of size. See the Thailand eSIM collection.
| Data | SimCorner | Global Starlink |
|---|---|---|
| 1GB | 7 days, A$5.00 | None |
| 3GB | 30 days, A$8.00 | None |
| 5GB | 30 days, A$10.50 | None |
| 10GB | 30 days, A$14.00 | None |
| 15GB | None | 7 days, A$15.90 (TrueMove) |
| 20GB | 30 days, A$25.00 | None |
| 30GB | 30 days, A$45.00 | None |
| 35GB | None | 7 days, A$16.90 (DTAC) |
| 50GB | 45 days, A$50.00 | 10 days, A$16.90 (TrueMove) |
| Unlimited | 5 days, A$27.00; 8 days, A$38.50; 16 days, A$56.00; 22 days, A$65.00; 30 days, A$70.00 | 10 days, A$22.90 (DTAC); 15 days, A$35.90 (DTAC) |
Our longest Thailand plan is 15 days and our lowest price is A$15.90. SimCorner's 10GB plan is A$14.00 for 30 days: cheaper and longer than our entry option. For short, heavy use the picture reverses: our 50GB for 10 days is A$16.90 against A$50.00 for 50GB over 45 days. Our DTAC 35GB (7 Days) and DTAC Unlimited (10 Days) allowances are a promotion for eSIMs activated by 31 December 2026; after that date they revert to 15GB and 50GB.
Vietnam eSIM prices
Both stores name Viettel and Vinaphone. Our fixed-data plans run on Vinaphone for 30 days, so most rows compare the same validity. See the Vietnam eSIM collection.
| Data | SimCorner | Global Starlink |
|---|---|---|
| 1GB | 7 days, A$5.00 | None |
| 3GB | 30 days, A$12.00 | None |
| 5GB | 30 days, A$14.00 | None |
| 10GB | 30 days, A$25.00 | 30 days, A$12.90 |
| 20GB | 30 days, A$40.00 | 30 days, A$18.90 |
| 30GB | 30 days, A$60.00 | 30 days, A$28.90 |
| 50GB | 45 days, A$69.00 | 30 days, A$33.90 |
| Daily allowance | Unlimited eSIM (3GB per day at full speed): 5 days, A$28.00; 8 days, A$41.00; 16 days, A$66.00; 22 days, A$83.00; 30 days, A$110.00 | Viettel 5GB per day: 7 days, A$15.90; 15 days, A$29.90; 30 days, A$55.90 |
From 10GB to 30GB the validity is identical and our prices are lower. The last row is not like for like: SimCorner's plan continues at reduced speed after 3GB each day, while our Viettel plan gives 5GB each day and is not described as unlimited.
South Korea eSIM prices
SimCorner names LG U+, SKT and KT. Our South Korea eSIM uses LG U+ only. Plans are in the South Korea eSIM collection.
| Data | SimCorner | Global Starlink |
|---|---|---|
| 1GB | 7 days, A$5.00 | None |
| 3GB | 30 days, A$12.00 | None |
| 5GB | 30 days, A$14.00 | None |
| 10GB | 30 days, A$27.00 | 3 days, A$7.90; 7 days, A$8.90; 15 days, A$9.90; 30 days, A$10.90 |
| 20GB | 30 days, A$43.00 | 7 days, A$15.90; 15 days, A$17.90; 30 days, A$18.90 |
| 30GB | 30 days, A$60.00 | 7 days, A$21.90; 15 days, A$24.90; 30 days, A$25.90 |
| 50GB | 45 days, A$69.00 | None |
| Unlimited | 4 days, A$30.00; 7 days, A$45.00; 10 days, A$55.00; 15 days, A$70.00; 30 days, A$99.00 | None |
Our 30-day plans at 10GB, 20GB and 30GB compare the same validity. Our range stops at 30GB; SimCorner goes on to 50GB and unlimited plans.
Multi-country Asia eSIM prices
SimCorner's Asia regional plan lists 29 destinations. Our Asia Explorer eSIM covers 12: Japan, South Korea, Taiwan, Hong Kong, Macau, Thailand, Vietnam, Malaysia, Singapore, Indonesia, Australia and New Zealand. It does not include mainland China. Check each list against your route before comparing prices. Our regional options are in the Asia eSIM collection.
| Data | SimCorner (29 destinations) | Global Starlink (12 destinations) |
|---|---|---|
| 1GB | 7 days, A$5.00 | None |
| 3GB | 30 days, A$13.00 | 3 days, A$5.90 |
| 5GB | 30 days, A$19.00 | None |
| 10GB | 30 days, A$34.00 | 7 days, A$12.90; 30 days, A$15.90 |
| 20GB | 30 days, A$55.00 | 7 days, A$20.90; 15 days, A$25.90; 30 days, A$27.90 |
| 30GB | 30 days, A$80.00 | 15 days, A$36.90; 30 days, A$39.90 |
| 50GB | 45 days, A$85.00 | 15 days, A$52.90; 30 days, A$61.90 |
| Unlimited | 5 days, A$25.00; 8 days, A$37.00; 16 days, A$69.00; 22 days, A$87.00; 30 days, A$101.00 | None |
Our 3GB plan lasts 3 days and SimCorner's lasts 30. From 10GB upwards our 30-day plans are priced lower, for fewer destinations.
Where SimCorner is the better choice
- Unlimited plans. SimCorner sells an Unlimited eSIM for Japan, China, Vietnam and South Korea. We have none for those four countries.
- Small, low-cost plans. SimCorner has a 1GB plan for 7 days at A$5.00 in every country above, plus 3GB and 5GB plans. In China, Vietnam and South Korea our smallest plan is 10GB.
- Thirty days on small plans. Its 3GB, 5GB and 10GB plans run for 30 days, so a light user on a long trip may pay less per day than with our shorter plans.
- Top-ups. SimCorner's Data eSIM can be topped up in its app. Our five country eSIMs cannot be topped up with data; you buy a second eSIM instead.
- More regional destinations. Its Asia regional plan lists 29 destinations against our 12.
- Support hours. SimCorner states a "24/7 human-led support desk" by email and contact form. Our Melbourne-based team is available 16 hours a day by live chat and email.
What differs beyond price
A Thai phone number
Both SimCorner lines are data-only. Every option on our Thailand eSIM comes with a local Thai (+66) number that can receive SMS, which is enough to register for apps such as Grab. Voice calls are included only on the DTAC Unlimited (15 Days) option: unlimited local calls in Thailand, free incoming calls, and 30 minutes of calls to Mainland China, Hong Kong, Macau, Taiwan, India, South Korea and Vietnam. The other four options have no call credit included, so you need to top up the number before you can make calls, or simply use LINE, WhatsApp or FaceTime over data.
China networks and the China and Hong Kong plan
Our mainland China eSIM connects to China Unicom, China Telecom or China Mobile. We also sell a combined China & Hong Kong eSIM that covers mainland China, Hong Kong and Macau on one plan, using China Telecom in mainland China and Macau and CSL in Hong Kong. Over 30 days it costs A$19.90 for 10GB, A$23.90 for 20GB or A$31.90 for 30GB. We did not record whether SimCorner's China plan works in Hong Kong or Macau, so confirm that on its site.
What "unlimited" means, and what happens after your allowance
SimCorner's Unlimited eSIM gives 3GB per day at full speed, then 128kbps, resetting every 24 hours. Japan is the exception: its Japan Unlimited is described as having no daily cap, with a hotspot limit of 3GB, 6GB, 9GB, 15GB or 30GB on the 4, 7, 10, 15 and 31-day plans.
Our plans differ by country:
- Japan: once the full-speed allowance is used, data continues at 256 kbps until the plan ends.
- China: after the high-speed allowance, data continues at 128 kbps until the plan ends.
- Vietnam: on the Vietnam eSIM Viettel option the 5GB allowance renews the next day; a Vinaphone fixed plan cannot be recharged.
- South Korea and Thailand: the plans cannot be recharged.
Hotspot, ID and when the clock starts
Hotspot is allowed on SimCorner's Data eSIM and on all five of our country eSIMs, none of which needs ID. On the Asia Explorer eSIM, travellers using it in Hong Kong or Taiwan must complete real-name registration with a valid passport.
SimCorner's Data eSIM validity starts on connecting at the destination, as do our Japan, China and South Korea eSIMs. Our Thailand and Vietnam eSIMs differ: service starts on the first QR code scan, even outside the country, so scan those just before you fly or after you land.
Which should you choose?
- Light user on a long stay, or you want top-ups: SimCorner's 3GB or 5GB plans for 30 days fit well.
- Unlimited data in Japan, China, Vietnam or South Korea: SimCorner sells it and we do not.
- 10GB to 30GB for South Korea, Vietnam or China: our 30-day plans were priced lower when we checked.
- Thailand with SMS verification or local calls: our Thailand eSIM includes a Thai number.
- Mainland China plus Hong Kong or Macau: our combined plan covers all three.
- Many countries on one trip: compare the destination lists, 29 against 12.

Frequently asked questions
Is Global Starlink cheaper than SimCorner for Asia eSIMs?
It depends on the plan. On 11 November 2026 our 30-day plans from 10GB to 30GB for South Korea, Vietnam and China had lower list prices, for example A$10.90 against A$27.00 for 10GB in South Korea. SimCorner was lower for small plans, such as 1GB for 7 days at A$5.00, and its 10GB Thailand plan at A$14.00 was below our lowest Thailand price of A$15.90.
Does SimCorner have plans that Global Starlink does not?
Yes. SimCorner sells unlimited eSIMs for Japan, China, Vietnam and South Korea, 1GB and 3GB plans, top-ups through its app, and an Asia regional plan listing 29 destinations against our 12.
Are the prices in this comparison still current?
They were read from each store's website on 11 November 2026, in Australian dollars, before checkout. Prices change, so check both sites before you buy.
Why do the validity periods differ for the same data size?
SimCorner's fixed-data plans mostly run for 30 days. We sell many sizes in 7, 15 and 30-day lengths. Compare validity as well as price, because a shorter plan with a lower price can cost more per day.
Can I top up a Global Starlink eSIM if I run out of data?
No. Our Japan, China, Thailand, Vietnam and South Korea eSIMs cannot be topped up with more data or extended, but you can buy another eSIM at any time. SimCorner's Data eSIM can be topped up in its app.
