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 verified coupon code as of August 2026. 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。

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 ===

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8月10日查证）
这才是你们要的对吧？全网搜刮了一遍，2026年8月还能用的优惠码：
| 品牌 | 优惠码 | 折扣 | 备注 |

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。旧码
WELCOME15、FIRST10、ESIM10已确认失效，别再试了。
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 [email protected]，那么：
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
[email protected] → Airalo 首单85折
[email protected] → Airalo 首单85折（又一次）
[email protected] → 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 + NEWTOAIRALO15 = $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?
Quick answer: yes, ultra-cheap eSIM works. SuperAlink’s $1.36 Southeast Asia plan delivered 25-42 Mbps in our real-world tests, fine for maps, messaging, and video. The trade-offs are a hard 1GB daily cutoff, no tethering, and no support. Heavier users should pay $8 for Airalo’s 3GB plan instead.
Last verified: August 10, 2026
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.

Pro Tips for Maximizing Savings
1. Gmail Alias Trick
Gmail supports + aliases. If your email is [email protected], then [email protected] and [email protected] 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 + NEWTOAIRALO15 = ~$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.
FAQ
Is a $1.36 eSIM safe to use?
In our testing, yes. SuperAlink delivered a working QR code within 30 seconds and rode legitimate local networks (TrueMove H in Thailand). The risk is not safety but service: hard daily data cutoffs, no tethering, and effectively no customer support.
What is the best coupon code for a cheap eSIM in August 2026?
Airalo’s official NEWTOAIRALO15 gives new users 15% off through December 31, 2026. On orders under $20, the $3 referral credit (code ESIMSCHOOL) saves more. For Holafly, the official MYESIMNOW5 gives 5% off.
Ultra-cheap eSIM or a bigger plan: which should I buy?
For 3-5 day trips with light use (maps, messaging, some social media) and hotel WiFi as backup, an ultra-cheap daily-cap plan is enough. For trips over 7 days, video calls, or tethering, pay for a 3-5GB metered plan; the experience gap is dramatic.
