各品牌详细优惠攻略

1. Airalo — 推荐码最划算

Airalo是目前用户量最大的eSIM平台，优惠方式主要是推荐码系统。

怎么薅：

• 新用户用推荐码注册，双方各得$3
• 等于首单直接便宜$3，买个$4.5的1GB日本套餐只要$1.5
• 用完这$3还可以把你自己的推荐码发给朋友，又赚$3

隐藏福利：

• Airalo偶尔会有季节促销（黑五、新年），全场-15%~20%
• App内偶尔弹窗推送限时码，保持通知开启
• 买区域套餐（亚洲/欧洲包）比单国家套餐的单价更低

实测价格对比 (日本 10GB/30天):
原价:       $11.00
用推荐码:    $8.00  (省$3)
黑五叠加:    $6.80  (再-15%)
信用卡2%返: $6.66  (再省$0.14)
总省:        $4.34 = 省39%

2. Holafly — KOL码满天飞

Holafly主打无限流量，价格偏贵，但到处都有博主折扣码。

怎么薅：

• YouTube/小红书搜”Holafly优惠码”，大把博主有5%折扣码
• 官方合作伙伴码一般是 -5%
• 偶尔有博主能给到 -10%，但不多

注意事项：

• Holafly的”无限”有公平使用政策，重度使用会限速
• 5%听起来不多，但Holafly本身贵，东南亚7天无限要$27，省5%就是$1.35
• 大促的时候（黑五/旅游旺季前）可能有全场-15%

实测价格对比 (泰国 7天无限):
原价:         $27.00 / ¥196
用5%码:       $25.65 / ¥186  (省¥10)
黑五-15%叠加: $22.95 / ¥166  (省¥30)

3. Saily — NordVPN用户专属

Saily是NordVPN旗下的eSIM品牌，2024年才推出。目前处于扩张期，折扣力度最大。

怎么薅：

• 新用户首单 -15%，码 SAILY15
• 已经在用NordVPN的，捆绑购买 -20%
• Saily的基础价格本来就比Airalo便宜，再打折就是性价比之王

真香案例：

日本 5GB/30天:
Airalo:  $11.00
Saily:   $8.99
Saily折后: $7.64  (用SAILY15)
差价:     $3.36 = 省30%

4. aloSIM — 新用户必撸

aloSIM是加拿大品牌，在北美市场比较强，亚洲覆盖也在扩展。

怎么薅：

• 新用户码 WELCOME10 打九折
• 不定期有 ALOSIM20 打八折（一般节日前后）
• 价格中等偏低，打完折和Airalo差不多

5. Nomad — 推荐系统

Nomad的推荐系统和Airalo类似，推荐一个人赚$3。

怎么薅：

• 推荐链接注册，双方各得$3
• Nomad的套餐选择比Airalo少，但覆盖区域不错
• 适合和朋友一起出游时互相推荐

6. KnowRoaming — 联盟链接

KnowRoaming比较特殊，没有传统意义上的优惠码，但是用联盟链接购买可以打折。

怎么薅：

• 通过联盟链接购买 -10%
• 365天Cookie有效期，点了链接一年内购买都有效
• 价格偏贵，但打完折也可以接受

7. SuperAlink — 小众但便宜

SuperAlink在华人圈比较流行，合作码 DONG00001 可以打95折。

薅羊毛进阶技巧

好，上面是基础操作。下面是进阶玩法，老司机专属。

技巧1: 邮箱别名无限注册

很多eSIM平台的新用户优惠只能用一次。但如果你有Gmail，可以用别名功能：

你的邮箱: yourname@gmail.com
别名1:    yourname+esim1@gmail.com
别名2:    yourname+esim2@gmail.com
别名3:    yourname+esim3@gmail.com

所有邮件都会收到同一个邮箱，但平台会认为是不同账号。不保证所有平台都有效，但亲测Airalo可以。

⚠️ 灰色地带警告：这招不违法但可能违反TOS。用不用你自己决定。

技巧2: 推荐码互换群

加入eSIM推荐码交换群（Reddit、Telegram、Discord都有），你推荐别人赚$3，别人推荐你也赚$3。

常用交换平台：

• Reddit: r/esim, r/airalo
• Telegram: 搜”eSIM referral exchange”
• NodeSeek/V2EX: 相关帖子评论区

技巧3: 学生折扣

部分eSIM品牌有学生优惠，但不会主动宣传：

• Holafly: 有edu邮箱认证的学生优惠（不定期）
• Saily: NordVPN学生版自动关联
• 一些品牌通过UNiDAYS/StudentBeans提供折扣

技巧4: 信用卡返现叠加

eSIM是线上消费，可以叠加信用卡的线上购物返现：

招商银行网上购物:  +1%返现
浦发梦卡:         +3%海淘返现 (eSIM品牌多为海外商户)
中信亚马逊联名:    +2%海淘返现
美国运通:          不定期海淘5x积分

叠加示例：

1. eSIM优惠码 -15%
2. 信用卡返现 -3%
3. 推荐码 -$3
4. 总省: 20%+

技巧5: 等大促

每年有几个确定会打折的时间窗口：

大促	时间	预期折扣	参与品牌
黑色星期五	11月下旬	-15%~30%	几乎所有
双11	11月11日	-10%~20%	华人品牌
新年促销	12月下旬~1月	-10%~15%	多数品牌
暑假促销	6月~7月	-5%~15%	Airalo, Holafly
春节/CNY	1月~2月	-10%	华人品牌

💡 如果你的旅行不急，提前1-2个月关注，等到大促再买。

真实省钱案例

说了这么多，来看看实际能省多少钱。

案例1: 日本7天游

需求: 日本 10GB / 7天

原价购买 Airalo:         $11.00 / ¥80
用推荐码:                $8.00  / ¥58
换 Saily + SAILY15:      $7.64  / ¥55
再叠加信用卡3%返现:      $7.41  / ¥54

最终省: ¥26 = 省33%

案例2: 欧洲15天游

需求: 欧洲 20GB / 15天

原价购买 Holafly无限:    $57.00 / ¥413
用5%博主码:              $54.15 / ¥393
黑五期间叠加-15%:        $45.90 / ¥333
信用卡2%:                $44.98 / ¥326

最终省: ¥87 = 省21%

案例3: 东南亚1个月

需求: 东南亚多国 / 30天

原价 Airalo 亚洲包 20GB: $37.00 / ¥268
推荐码:                  $34.00 / ¥247
非促销期无叠加

最终省: ¥21 = 省8%

vs. 买Saily单国家包×3:   $24.00 / ¥174
用SAILY15:               $20.40 / ¥148

省更多: ¥120 = 省45%  🔥

🔥 关键发现: 有时候换品牌比用优惠码省更多。先比价，再找码。

过期优惠码墓地 ⚰️

以下码已经过期或失效，别再试了：

品牌	过期码	原折扣	失效时间
Airalo	SUMMER25	-25%	2025年9月
Holafly	HOLA20	-20%	2025年12月
Saily	LAUNCH30	-30%	2025年6月
aloSIM	BF2025	-25%	2025年12月

注意事项

⚠️ 别踩这些坑

1. 一个优惠码只能用一次 — 别以为复制粘贴就能反复用
2. 推荐码不能和优惠码叠加 — 大多数平台只能选一个
3. 优惠码有最低消费 — 有些码要满$10才能用
4. 别买到假码 — 某些网站卖”VIP优惠码”，都是骗子
5. 汇率波动 — 美元定价的eSIM，人民币实付会随汇率变

如何验证优惠码是否有效

步骤：
1. 选好套餐，加入购物车
2. 在结账页面输入优惠码
3. 看价格是否变化
4. 如果显示"Invalid"→ 码已过期
5. 如果价格没变 → 可能有最低消费限制
6. 换一个码试试

每月更新承诺

我会在每月初更新这篇文章，验证所有优惠码。

如果你发现了新优惠码，欢迎在评论区留言！我验证后会加到表格里，并@你。

如果某个码失效了，也请告诉我，我会及时移到过期墓地。

💰 总结: eSIM省钱的核心思路就三步 — ① 先比价选最便宜的品牌 ② 再用优惠码打折 ③ 叠加信用卡返现。按这个顺序来，每次出国至少省20%。

Stop paying full price for eSIM. These coupon codes will save you up to half.

I’ve been buying travel eSIMs since 2024 — over 30 purchases and counting. At first, I paid full price like a chump. Then I discovered that almost every eSIM brand has discount codes, referral bonuses, and seasonal sales. Stack them with credit card cashback, and you’re looking at 50%+ savings.

This is my master list of every working eSIM coupon code I know. Updated monthly. If you find a new code or one of these has expired, drop a comment and I’ll update ASAP.

Last verified: March 2026

Brand-by-Brand Breakdown

1. Airalo — Referral Codes Are King

Airalo is the biggest eSIM marketplace. Their primary savings mechanism is the referral system: both parties get $3 when a new user signs up with a referral code.

How to save:

• Use referral code at signup → both get $3 credit
• A $4.50 Japan 1GB plan becomes $1.50 after referral credit
• Share your own code with friends for another $3 each
• Watch for seasonal sales (Black Friday, New Year) with 15-20% off sitewide
• Keep app notifications on — they occasionally push flash deals

Real price example (Japan 10GB/30 days):
Full price:           $11.00
With referral:        $8.00  (save $3)
Black Friday -15%:    $6.80  (save another $1.20)
Credit card 2% back:  $6.66  (save $0.14)
Total saved:          $4.34 = 39% off

2. Holafly — Influencer Codes Everywhere

Holafly specializes in unlimited data plans. They’re pricier than competitors, but influencer discount codes are abundant.

• Search YouTube or blogs for “Holafly discount code” — most travel creators have a 5% code
• Official partner codes give -5%
• Some high-profile creators negotiate -10%
• Black Friday / peak travel season may bring sitewide -15%

3. Saily — Best Discounts Right Now

Saily is NordVPN’s eSIM brand, launched in 2024. They’re still in growth mode, meaning the deepest discounts.

• New users: -15% with SAILY15
• NordVPN subscribers: -20% bundle discount
• Already cheaper than Airalo at base price — discounts make it a no-brainer

Japan 5GB/30 days:
Airalo:              $11.00
Saily:               $8.99
Saily with SAILY15:  $7.64
Difference:          $3.36 = 30% cheaper

4-7. aloSIM, Nomad, KnowRoaming, SuperAlink

• aloSIM: New user code WELCOME10 for 10% off. Occasional ALOSIM20 for 20%.
• Nomad: Referral system like Airalo, $3 for both parties.
• KnowRoaming: No traditional codes, but affiliate links give 10% off with a 365-day cookie.
• SuperAlink: Popular in Chinese-speaking markets, code DONG00001 for 5% off.

Advanced Money-Saving Tactics

Tactic 1: Email Aliases for Multiple “New” Accounts

Gmail lets you create aliases that all route to the same inbox:

Your email:  yourname@gmail.com
Alias 1:     yourname+esim1@gmail.com
Alias 2:     yourname+esim2@gmail.com

Some platforms treat these as separate accounts, letting you reuse new-user discounts. Not all platforms fall for this — tested working on Airalo.

⚠️ Gray area: Not illegal, but may violate Terms of Service. Your call.

Tactic 2: Referral Code Exchange Communities

Join referral code swap groups on Reddit (r/esim, r/airalo), Telegram, or Discord. You refer someone, they refer you back — everyone gets $3.

Tactic 3: Student Discounts

Some brands offer student pricing through edu email verification, UNiDAYS, or StudentBeans. Holafly and Saily (via NordVPN student plan) are the most common.

Tactic 4: Credit Card Cashback Stacking

eSIM purchases are online transactions. Stack with credit cards that offer elevated online shopping or international purchase rewards:

1. eSIM coupon code: -15%
2. Credit card cashback: -2-3%
3. Referral credit: -$3
4. Total savings: 20%+

Tactic 5: Wait for Sales

Key sale windows every year:

Sale	Timing	Expected Discount	Brands
Black Friday	Late November	-15% to -30%	Almost all
New Year	Late Dec - Jan	-10% to -15%	Most brands
Summer Sale	June - July	-5% to -15%	Airalo, Holafly

If your trip isn’t urgent, watch for these windows and buy 1-2 months ahead.

Real Savings Examples

Example 1: 7-Day Japan Trip

Need: Japan 10GB / 7 days

Airalo full price:           $11.00
With referral code:          $8.00
Switch to Saily + SAILY15:   $7.64
Credit card 3% cashback:     $7.41

Total saved: $3.59 = 33%

Example 2: 15-Day Europe Trip

Need: Europe 20GB / 15 days

Holafly unlimited full price:  $57.00
With 5% influencer code:       $54.15
Black Friday -15% stacked:     $45.90
Credit card 2% cashback:       $44.98

Total saved: $12.02 = 21%

Example 3: 30 Days in Southeast Asia

Need: Multi-country / 30 days

Airalo Asia pack 20GB:    $37.00
With referral:            $34.00

OR: Saily single-country ×3:  $24.00
With SAILY15:                  $20.40

Save: $16.60 = 45%  🔥

Key insight: Sometimes switching brands saves more than any coupon code. Compare prices first, then find codes.

Expired Codes (Don’t Bother)

Brand	Expired Code	Was	Died
Airalo	SUMMER25	-25%	Sept 2025
Holafly	HOLA20	-20%	Dec 2025
Saily	LAUNCH30	-30%	June 2025
aloSIM	BF2025	-25%	Dec 2025

Things to Watch Out For

1. One code per purchase — most platforms don’t allow stacking coupon + referral
2. Minimum spend requirements — some codes need $10+ cart
3. Fake “VIP codes” — any site selling coupon codes is a scam
4. Currency fluctuations — USD-priced eSIMs fluctuate with your local currency

Monthly Update Promise

I verify every code on this page at the start of each month. Found a new code? Know one that’s expired? Drop a comment and I’ll update the list with credit to you.

Bottom line: The eSIM savings playbook is simple: ① Compare prices across brands first ② Apply the best coupon code ③ Stack credit card cashback. Follow this order and save at least 20% every trip.
