I Tested a $1.36 eSIM Plan — Is Ultra-Cheap eSIM Actually Usable?
We tested the cheapest eSIM plans on the market — from $1.36 SuperAlink to $4.50 Airalo — with real speed tests, daily cost breakdowns, and every coupon code we could find. Here's whether ultra-budget eSIM is worth it.
花了不到10块人民币，出国用了4天5G流量。eSIM真的卷到这个价格了？
我最近出了趟东南亚，专门测试了市面上最便宜的几个eSIM方案。结论先放：能用，但有坑。
测试方案一览
先上对比表，后面逐个详细说：
| 品牌 | 套餐 | 价格 | 折合人民币 | 每天成本 | 流量 | 有效期 |
|---|---|---|---|---|---|---|
| SuperAlink | 东南亚4天 | $1.36 | ¥9.8 | ¥2.5/天 | 1GB/天 | 4天 |
| Airalo | 泰国1GB | $4.50 | ¥32.4 | — | 1GB | 7天 |
| aloSIM | 泰国1GB | $4.00 | ¥28.8 | — | 1GB | 7天 |
| Saily | 泰国1GB | $3.99 | ¥28.7 | — | 1GB | 7天 |
| GlocalMe | 泰国3天 | $2.10 | ¥15.1 | ¥5.0/天 | 500MB/天 | 3天 |
没错，SuperAlink 1.36美金，折合人民币不到10块钱。比一杯奶茶还便宜。
实测1：SuperAlink $1.36（东南亚4天）
这个价格我买的时候自己都不信。
购买过程
在SuperAlink官网注册 → 选东南亚套餐 → Apple Pay付款 → 30秒收到QR码。整个过程丝滑得不像这个价位。
网速实测
测试地点：曼谷素万那普机场 → 市区Siam → 清迈古城

=== SuperAlink 清迈古城 ===
下载: 25.6 Mbps

延迟: 52ms42Mbps下载速度——刷抖音、看YouTube、视频通话全都没问题。说实话这个网速比我家WiFi都快。
实际使用体验
- Google Maps导航：秒开，无卡顿
- 微信消息/语音：正常
- 刷小红书/抖音：流畅，视频秒加载
- 视频通话：画面清晰，偶尔有0.5秒延迟
- 打车App（Grab）：定位准确，司机电话正常接
但是！有坑
- 每日流量1GB用完直接断网，不是降速，是断。第2天在清迈刷视频用超了，下午3点就没网了。
- 不支持热点分享。想开热点给同伴用？不行。
- 客服基本没有。1.36美金你还想要什么客服？
性价比评分：⭐⭐⭐⭐（4/5）
轻度使用完全够了。重度用户别想了。
实测2：Airalo $4.50（泰国1GB）
Airalo是eSIM圈最大的平台，用户量最多，但最低档套餐只有1GB。
网速实测
=== Airalo 曼谷 Speed Test ===
下载: 55.8 Mbps
上传: 12.3 Mbps
延迟: 28ms
网络: AIS (4G+)
=== Airalo 清迈 ===
下载: 41.2 Mbps
上传: 9.8 Mbps
延迟: 38ms比SuperAlink快了30%左右，走的AIS网络，信号覆盖更好。
使用感受
- App体验是几个里面最好的，购买-安装-激活一条龙
- 1GB其实不太够用。我节省着用，3天就用完了
- 用完之后可以在App里直接充值，但续费价格不便宜
性价比评分：⭐⭐⭐（3/5）
品质最好，但1GB实在太少。建议直接买3GB档（$8起）。
实测3：aloSIM $4.00（泰国1GB）
aloSIM比Airalo便宜5毛，套餐几乎一样。
=== aloSIM 曼谷 Speed Test ===
下载: 35.7 Mbps
上传: 6.4 Mbps
延迟: 45ms
网络: DTAC (4G)走的DTAC网络，速度比AIS慢一些，但完全够用。App界面简洁，没有Airalo花哨，但该有的都有。
性价比评分：⭐⭐⭐⭐（4/5）
比Airalo便宜，体验差不多。预算有限选这个。
实测4：Saily $3.99（泰国1GB）
Saily是NordVPN团队做的eSIM品牌，去年才上线，主打安全。
=== Saily 曼谷 Speed Test ===
下载: 48.2 Mbps
上传: 10.1 Mbps
延迟: 32ms
网络: AIS (4G+)跟Airalo走一样的AIS网络，速度接近。多了个卖点是”增强隐私保护”，但实际用起来感觉不出差别。
性价比评分：⭐⭐⭐⭐（4/5）
NordVPN老用户可以考虑，App质量不错。
每GB成本对比（关键！）
按每GB成本排名：
| 排名 | 品牌 | 每GB成本 | 每GB人民币 |
|---|---|---|---|
| 🥇 | SuperAlink | $0.34/GB | ¥2.4 |
| 🥈 | GlocalMe | $1.40/GB | ¥10.1 |
| 🥉 | Saily | $3.99/GB | ¥28.7 |
| 4 | aloSIM | $4.00/GB | ¥28.8 |
| 5 | Airalo | $4.50/GB | ¥32.4 |
SuperAlink的每GB成本是Airalo的十三分之一。价差离谱。
但便宜有便宜的代价：不能热点、超量断网、无客服。你为省下的钱付出的是体验和保障。
优惠码合集（2026年3月实测有效）
这才是你们要的对吧？全网搜刮了一遍，亲测有效的优惠码：
| 品牌 | 优惠码 | 折扣 | 备注 |
|---|---|---|---|
| Airalo | ESIMSCHOOL | 首单85折 | 新用户 |
| Airalo | WELCOME15 | 首单85折 | 有时失效，试试看 |
| Holafly | ESIMSCHOOL | 5%折扣 | 全部套餐 |
| Saily | 通过官网链接 | 首单9折 | 不定期活动 |
| aloSIM | FIRST10 | 首单9折 | 新用户专享 |
| Nomad | ESIM10 | 10%折扣 | 全部套餐 |
| Ubigi | 无需优惠码 | App内活动价 | 留意App推送 |
优惠码这东西有时效性，如果失效了在评论区说一声，我会更新。
薅羊毛进阶技巧
这些方法我都亲测过，确实管用：
1. 邮箱别名注册多号
Gmail支持+别名。比如你的邮箱是 example@gmail.com，那么：
example+airalo1@gmail.comexample+airalo2@gmail.com
都会收到同一个邮箱，但平台认为是不同用户。新用户优惠无限薅。
# 用这些别名注册不同账号，每个都能享受首单优惠
example+airalo1@gmail.com → Airalo 首单85折
example+airalo2@gmail.com → Airalo 首单85折（又一次）
example+saily1@gmail.com → Saily 首单9折2. Referral邀请码互刷
大部分eSIM平台都有邀请返现：
| 平台 | 邀请奖励 | 方式 |
|---|---|---|
| Airalo | 邀请人$3 + 被邀请$3 | App内分享链接 |
| Holafly | 邀请人$3 + 被邀请5%折扣 | 分享链接 |
| Nomad | 邀请人$3 + 被邀请$3 | App内邀请 |
两个人互相邀请，各省$3。一杯咖啡钱有了。
3. 关注品牌社交媒体
Airalo和Saily经常在Twitter/X上搞闪购活动，有时候能遇到30%-50%折扣。设置通知别错过。
4. 错峰购买
黑五/双十一/圣诞节前后各大平台都会打折。如果行程不急，等大促再买。
谁适合超低价方案？
适合超低价eSIM的人：
- 出行3-5天的短途旅行
- 只用导航+消息+偶尔查东西
- 有WiFi补充（酒店/咖啡厅）
- 不需要热点分享
- 能接受”用完断网明天再来”
该多花点钱的人：
- 出行7天以上
- 需要视频通话/直播/远程办公
- 要开热点给同伴用
- 去偏远地区需要稳定信号
- 需要客服支持（出差、商务）
我的建议：短途轻度用户，SuperAlink $1.36香到不行。其他情况，多花20块买Airalo 3GB档（$8），体验完全不一样。
终极性价比方案
综合测试结果，我推荐的分档方案：
| 预算 | 方案 | 适合 |
|---|---|---|
| 极致省钱 | SuperAlink $1.36 | 3-4天短途，轻度上网 |
| 性价比之选 | Airalo 3GB $8 + 优惠码85折 = $6.8 | 5-7天旅行，日常使用 |
| 舒适型 | Saily 5GB $11.99 | 7-10天，中度使用 |
| 无脑型 | Holafly无限流量 $19/5天 | 重度用户，不想操心 |
最后说一句：eSIM的价格战对消费者是好事。 两年前出国买流量动辄大几十甚至上百人民币，现在10块钱就能搞定。卷下去，卷下去。
I Tested a $1.36 eSIM Plan — Is Ultra-Cheap eSIM Actually Usable?
I spent less than $1.50 on mobile data for a 4-day trip abroad. eSIM prices have gotten this competitive.
I recently took a trip to Southeast Asia and deliberately tested the cheapest eSIM plans on the market. The verdict: usable, but with trade-offs.
The Plans I Tested
| Brand | Plan | Price | Cost/Day | Data | Validity |
|---|---|---|---|---|---|
| SuperAlink | SE Asia 4-day | $1.36 | $0.34/day | 1GB/day | 4 days |
| Airalo | Thailand 1GB | $4.50 | — | 1GB | 7 days |
| aloSIM | Thailand 1GB | $4.00 | — | 1GB | 7 days |
| Saily | Thailand 1GB | $3.99 | — | 1GB | 7 days |
| GlocalMe | Thailand 3-day | $2.10 | $0.70/day | 500MB/day | 3 days |
Yes, SuperAlink at $1.36. Cheaper than a cup of coffee. Let’s see what that actually gets you.
Test 1: SuperAlink $1.36 (SE Asia, 4 Days)
I was skeptical at checkout. Less than a buck fifty for international data?
Purchase Experience
Signed up on SuperAlink’s site → selected the SE Asia plan → paid via Apple Pay → QR code delivered in 30 seconds. Surprisingly smooth for something this cheap.
Real Speed Tests
Testing locations: Bangkok Suvarnabhumi Airport → Siam city center → Chiang Mai old town.
=== SuperAlink Bangkok Airport ===
Download: 42.3 Mbps
Upload: 8.7 Mbps
Latency: 34ms
Network: TrueMove H (4G)
=== SuperAlink Bangkok Siam ===
Download: 38.1 Mbps
Upload: 7.2 Mbps
Latency: 41ms
=== SuperAlink Chiang Mai ===
Download: 25.6 Mbps
Upload: 5.1 Mbps
Latency: 52ms42 Mbps download — streaming, video calls, navigation all worked fine. Honestly faster than some hotel WiFi I’ve used.
Day-to-Day Usage
- Google Maps: Instant loading, zero lag
- Messaging apps (WhatsApp, WeChat): Flawless
- Social media scrolling: Smooth video playback
- Video calls: Clear picture, occasional 0.5s delay
- Ride-hailing (Grab): Accurate GPS, driver calls worked
The Catch
- Hard cutoff at 1GB/day. Not throttled — disconnected. On day 2, I burned through my allowance watching videos and lost connectivity at 3 PM.
- No tethering. Can’t share your connection.
- No customer support. At $1.36, you’re on your own.
Value Rating: 4/5
Perfect for light use. Power users, look elsewhere.
Test 2: Airalo $4.50 (Thailand, 1GB)
The biggest name in eSIM. Their entry-level plan is just 1GB, though.
Speed Tests
=== Airalo Bangkok ===
Download: 55.8 Mbps
Upload: 12.3 Mbps
Latency: 28ms
Network: AIS (4G+)
=== Airalo Chiang Mai ===
Download: 41.2 Mbps
Upload: 9.8 Mbps
Latency: 38msAbout 30% faster than SuperAlink, running on AIS — Thailand’s largest network with better rural coverage.
Verdict
Best app experience of the bunch. But 1GB runs out fast — I lasted 3 days being careful. You can top up in-app, but refill prices aren’t cheap.
Value Rating: 3/5
Best quality, but 1GB is too little. Go for the 3GB plan ($8+) instead.
Test 3: aloSIM $4.00 (Thailand, 1GB)
50 cents cheaper than Airalo, near-identical offering.
=== aloSIM Bangkok ===
Download: 35.7 Mbps
Upload: 6.4 Mbps
Latency: 45ms
Network: DTAC (4G)Runs on DTAC — slightly slower than AIS but perfectly adequate. Simple app, no frills, gets the job done.
Value Rating: 4/5
Cheaper than Airalo, similar experience. Good budget pick.
Test 4: Saily $3.99 (Thailand, 1GB)
Made by the NordVPN team, launched last year with a “privacy-first” pitch.
=== Saily Bangkok ===
Download: 48.2 Mbps
Upload: 10.1 Mbps
Latency: 32ms
Network: AIS (4G+)Same AIS network as Airalo, similar speeds. The “enhanced privacy” claim is hard to verify in practice — felt identical to everything else.
Value Rating: 4/5
Solid option, especially if you’re already a NordVPN user.
Cost Per GB Breakdown
Ranked by cost per GB:
| Rank | Brand | Cost/GB | Notes |
|---|---|---|---|
| 1 | SuperAlink | $0.34 | No tethering, hard data cap |
| 2 | GlocalMe | $1.40 | Daily cap 500MB |
| 3 | Saily | $3.99 | Good app, NordVPN backing |
| 4 | aloSIM | $4.00 | Simple, reliable |
| 5 | Airalo | $4.50 | Best app, largest selection |
SuperAlink costs one-thirteenth of Airalo per GB. The price gap is staggering.
But cheap has its trade-offs: no tethering, hard cutoffs, and zero support. You’re paying for the data and nothing else.
Every Coupon Code We Found (March 2026)

Pro Tips for Maximizing Savings
1. Gmail Alias Trick
Gmail supports + aliases. If your email is you@gmail.com, then you+airalo1@gmail.com and you+airalo2@gmail.com both land in your inbox — but platforms see them as different accounts. Unlimited first-order discounts.
2. Referral Code Stacking
Most platforms offer mutual rewards:
| Platform | Inviter Gets | Invitee Gets |
|---|---|---|
| Airalo | $3 credit | $3 credit |
| Holafly | $3 credit | 5% off |
| Nomad | $3 credit | $3 credit |
Invite a travel buddy, both save $3. Free coffee money.
3. Follow Social Media
Airalo and Saily run flash sales on X/Twitter — sometimes 30-50% off. Turn on notifications.
4. Buy During Sales Events
Black Friday, Cyber Monday, and year-end holidays bring platform-wide discounts. If your trip isn’t urgent, wait for a sale.
Who Should Buy Ultra-Cheap eSIM?
Ultra-cheap eSIM works for you if:
- Short trip (3-5 days)
- Light usage: maps, messaging, occasional browsing
- WiFi available at hotel/cafes as backup
- Solo use (no tethering needed)
- You can live with “data gone, wait till tomorrow”
Spend more if:
- Trip longer than 7 days
- Video calls, streaming, or remote work
- Tethering for travel companions
- Heading to remote areas needing reliable signal
- Business travel requiring customer support
My recommendation: For short, light trips, SuperAlink at $1.36 is an absurd bargain. For everything else, spend $8 on Airalo’s 3GB plan — the experience difference is dramatic.
The Best Deal at Every Budget
| Budget | Plan | Best For |
|---|---|---|
| Bare minimum | SuperAlink $1.36 | 3-4 day trips, light browsing |
| Best value | Airalo 3GB $8 + 15% code = ~$6.80 | 5-7 day trips, normal use |
| Comfortable | Saily 5GB $11.99 | 7-10 day trips, moderate use |
| No-stress | Holafly Unlimited $19/5 days | Heavy users, don’t want to think about it |
The eSIM price war is great news for travelers. Two years ago, international data cost $30-100+. Now you can get online for less than two dollars. Long may the competition continue.
