别傻傻原价买eSIM，这些优惠码帮你省一半。

我从2024年开始用eSIM出国，到现在买了不下30次。一开始老老实实原价付款，后来发现几乎每个品牌都有优惠码，而且叠加信用卡返现、等大促的话，最多能省50%+。

这篇文章我把所有亲测有效的优惠码整理成表，每月更新。如果你发现新码或者某个码失效了，评论区告诉我，我会第一时间更新。

各品牌详细优惠攻略

1. Airalo: 官方码 + 推荐码双管齐下

Airalo是目前用户量最大的eSIM平台。2026年的重点变化：Airalo放出了两个长期官方码，比推荐码力度更大。

怎么薅：

• 新用户: 官方码 NEWTOAIRALO15 首单85折，有效期到2026年12月31日（或10万次兑换用完为止），单笔最高减$100
• 新用户（本月另有一个）: 季节码 AUGUST15 同样首单85折，挂在Airalo官方优惠页。这类按月份命名的码会轮换，进9月前先去官方页确认一下
• 老用户: 官方码 AIRALOESIM10 9折，满$10可用，同样到2026年底
• 推荐码 ESIMSCHOOL 注册，双方各得$3（适合小额订单，$4.5的1GB套餐用15%码只省$0.68，用推荐码省$3）
• 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：

• 官方通用码 MYESIMNOW5 全场5%，任意目的地都能用
• 买月付订阅的话用官方码 MONTHLYPLAN10，10%，力度翻倍（但只对月付套餐生效，单次旅行eSIM用不了）
• 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: 学生党和推荐制福利

Saily是NordVPN旗下的eSIM品牌，2024年推出。注意：老码 SAILY15 已过期，别再用了。

怎么薅（2026年8月现状）：

• Saily官方维护一个 优惠码页面，不定期放码，出发前先去看一眼
• 学生折扣: 通过Student Beans认证打 -15%~25%（各地区档位不同，2026年8月多数地区显示15%，个别渠道给到25%），这是目前Saily力度最大的稳定折扣
• 推荐好友: 每成功推荐一人得 $5余额
• Saily的基础价格本来就比Airalo便宜，叠加学生折扣就是性价比之王

真香案例：

日本 5GB/30天:
Airalo:            $11.00
Saily:             $8.99
Saily学生-25%后:   $6.74  (按最高25%档计)
差价:              $4.26 = 省39%

4. aloSIM: 老码已死，看官网活动

aloSIM是加拿大品牌，在北美市场比较强，亚洲覆盖也在扩展。

2026年8月现状：

• 老码 WELCOME10 和 ALOSIM20 均无法验证仍然有效，已移入下方过期墓地
• 目前没有查证到稳定的官方通用码，首单结账时留意页面自动弹出的新用户优惠
• 价格中等偏低，原价也和Airalo打折后差不多

5. Nomad: 推荐系统 + 季节大促

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
• 2026年8月有多个渠道报道季节促销码 USA40（美国套餐-40%）和 STORY30（-30%），报道有效期至8月31日，两个码都要求单笔购买2张及以上eSIM。我们没能逐一实测，下单前自己在结账页试一下
• Nomad的套餐选择比Airalo少，但覆盖区域不错

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: [email protected]
别名1:    [email protected]
别名2:    [email protected]
别名3:    [email protected]

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：

• Saily: 通过Student Beans认证-15%~25%（2026年8月确认有效，多数地区显示15%）
• Holafly: 官网有Students页面，UNiDAYS上报道过12%折扣，但官方折扣页目前显示无常驻学生计划，属于”not yet confirmed”
• 一些品牌不定期通过UNiDAYS/StudentBeans上线活动，出发前搜一下

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
新用户官方码NEWTOAIRALO15:  $9.35  / ¥68
推荐码更划算(小额订单):     $8.00  / ¥58
再叠加信用卡3%返现:         $7.76  / ¥56

最终省: ¥24 = 省30%

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

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
学生党Student Beans -25% (最高档): $18.00 / ¥131

省更多: ¥116 = 省43%  🔥

🔥 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
Saily	SAILY15	-15%	2026年年中
aloSIM	WELCOME10	-10%	2026年 (无法再验证)
aloSIM	ALOSIM20	-20%	2026年 (无法再验证)
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%。

Brand-by-Brand Breakdown

1. Airalo — Official Codes Now Beat Referrals

Airalo is the biggest eSIM marketplace. The big 2026 change: Airalo published two official long-running promo codes that usually beat the referral credit.

How to save:

• New users: NEWTOAIRALO15 for 15% off your first order. Valid through December 31, 2026 (or until 100,000 total redemptions), max $100 discount per order
• Existing users: AIRALOESIM10 for 10% off orders of $10 or more, also through end of 2026
• Small orders: the referral code (ESIMSCHOOL) still wins. On a $4.50 plan, $3 referral credit beats 15% off
• 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 — Official Code Plus Influencer Codes

Holafly specializes in unlimited data plans. They’re pricier than competitors, but discounts are easy to find.

• MYESIMNOW5 is Holafly’s official 5% code, works sitewide on any destination
• MONTHLYPLAN10 is Holafly’s official 10% code for monthly plan subscriptions — double the discount, but it does not apply to one-off travel eSIMs
• Our partner code ESIMSCHOOL also gives -5%
• Search YouTube for “Holafly discount code” — some high-profile creators negotiate -10%
• Black Friday / peak travel season may bring sitewide -15%

3. Saily — Students Get the Best Deal

Saily is NordVPN’s eSIM brand, launched in 2024. Heads up: the old SAILY15 code has expired.

• Saily maintains an official rotating coupon page at saily.com/coupon — check it before you buy
• Students: 15%-25% off via Student Beans verification (the rate varies by region; 15% is the standard listing as of August 2026, with 25% appearing in some regions), the deepest stable Saily discount right now
• Referral program: $5 in Saily credits for every successful referral
• Already cheaper than Airalo at base price

Japan 5GB/30 days:
Airalo:                     $11.00
Saily:                      $8.99
Saily with student -25%:    $6.74  (max student tier)
Difference:                 $4.26 = 39% cheaper

4-7. aloSIM, Nomad, KnowRoaming, SuperAlink

• aloSIM: The old WELCOME10 and ALOSIM20 codes could not be re-verified in August 2026. No stable public code confirmed right now; watch for new-user offers at checkout.
• Nomad: Referral system like Airalo, $3 for both parties. Seasonal codes USA40 (40% off US plans) and STORY30 (30% off) are reported valid through August 31, 2026, and both require buying 2 or more plans in one order — we could not test every plan, so try them at checkout.
• 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:  [email protected]
Alias 1:     [email protected]
Alias 2:     [email protected]

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

Saily offers 15%-25% off through Student Beans verification, depending on region (confirmed August 2026). Holafly has a Students page and a reported 12% UNiDAYS deal, but its own discounts page currently lists no standing student program, so treat that one as not yet confirmed.

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 NEWTOAIRALO15 (-15%):      $9.35
With referral code (better):    $8.00
Credit card 3% cashback:        $7.76

Total saved: $3.24 = 30%

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 Student Beans -25% (max):    $18.00

Save: $16.00 = 43%  🔥

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
Saily	SAILY15	-15%	Mid 2026
aloSIM	WELCOME10	-10%	2026 (no longer verifiable)
aloSIM	ALOSIM20	-20%	2026 (no longer verifiable)
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

FAQ

What is the best eSIM promo code right now (August 2026)?

For most people it’s Airalo’s official NEWTOAIRALO15 (15% off for new users, valid through December 31, 2026). Existing Airalo users should use AIRALOESIM10 (10% off, $10 minimum). For Holafly, use the official MYESIMNOW5 for 5% off.

Can I stack an eSIM coupon code with a referral code?

Almost never. Airalo, Holafly, Saily, and Nomad all limit you to one code per order. Pick whichever saves more: on small orders (under $20) the flat $3 referral credit usually beats a percentage code; on bigger orders the percentage code wins.

Do eSIM student discounts exist?

Yes, but only a few are real. Saily offers 15%-25% off through Student Beans depending on region (15% is the standard listing we confirmed in August 2026). Holafly’s student discount is not yet confirmed as a standing program. Ignore any site claiming universal 12% student codes for every brand.

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.
