GUAC VS SAILY
Saily Is Good.
The Price Isn't.
Saily is a solid eSIM from the team behind NordVPN. But you're paying for the brand name, the affiliate army, and security features you don't need in a travel eSIM. Guac gives you the same travel data that works, for up to 65% less.

Unlimited plans: transparency vs fine print.
Both Guac and Saily offer unlimited data plans. The difference is what happens when you hit the speed limit, and how clearly it's disclosed before purchase.
Daily High-Speed Quota
- Saily
- "Unlimited" with a 5 GB/day high-speed cap. After 5 GB, speeds drop to 1 Mbps until midnight local time. The cap is not prominently disclosed at purchase. Their global "UNLIMITED" plans contain a finite 30 GB high-speed allowance. After that, speeds throttle to 1024 kbps (30-day plans) or 1 kbps (90-day plans). The word "unlimited" applies to connection duration, not speed.
- Guac
- You choose your own daily high-speed quota: 500 MB, 1 GB, 2 GB, 3 GB, 5 GB, or 10 GB/day. After the quota, you stay online at reduced speeds. Resets every 24 hours. The quota is displayed clearly before purchase.
Guac tells you upfront. Saily buries it in the fine print.
Hotspot / Tethering
- Saily
- Hotspot supported, but usage details are vague. No published daily hotspot cap (unlike Holafly's 1 GB/day), but no clear guarantee of full-speed tethering either.
- Guac
- Full data shareable via hotspot. No daily cap. Your entire purchased data or your full daily unlimited quota can be tethered to laptops, tablets, whatever you need.
Guac: share everything. No asterisks.

Buy now. Travel whenever.
Sometimes you find a deal months before your trip. Or your plans change. Here's where Guac gives you 6x more breathing room.
Saily
30 days. If you don't travel within 30 days, the plan auto-activates and the clock starts ticking on your data, even if you're still at home.
Guac
180 days. Buy your plan up to 6 months before your trip. It only activates when you connect at your destination. Zero waste.
Planning a trip for next summer? Buy your Guac eSIM now and it'll be waiting for you. With Saily, you'd need to buy within a month of departure or risk your plan activating at home.
More plans, more flexibility.
Saily offers a clean, simple set of plans. Guac gives you more options at both ends of the spectrum.

|---|---|---|
| Smallest standard plan | 1 GB | 1 GB |

Going for 2 weeks? Saily forces you into a 30-day plan and you pay for days you won't use. Guac has 15-day plans so you only pay for what you need. Staying 3 months? Guac has 90-day plans. Saily doesn't.
Cashback on every single plan.
Saily reserves cashback for their premium Ultra subscribers. Guac gives it to everyone.
Saily
8%, but only on Saily Ultra (monthly subscription). Standard prepaid plans get nothing.
Subscriptions
Saily Ultra auto-renews monthly.
Guac
5% on every single plan. No subscription required. Credited as Guac Credit for your next trip.
Subscriptions
Never. One-time purchases only. No auto-renew. Ever.
With Guac, your 5th trip basically pays for itself. Every purchase earns credit toward the next one. No premium subscription needed.
Share eSIMs with your travel group.
Traveling with friends or family? Guac lets you buy eSIMs and share them via a link. Gift data to travel companions without handing over your phone or account. Saily doesn't offer this.
Most travelers use less than they think.
Industry data shows the average traveler uses 3-5 GB per week. That means most people overpay for data they never touch.
Light Traveler (under 1 GB/day)
Maps, messaging, email, occasional social media. 2-3 GB per week.
Best Guac plan: 3 GB standard ($2.84 - $4.60)
Moderate Traveler (1-2 GB/day)
Social media, music streaming, photo sharing, video calls. 5-10 GB per week.
Best Guac plan: 5 GB standard ($4.37 - $6.46)
Heavy Traveler (2-3+ GB/day)
HD streaming, video calls, content creation, heavy hotspot usage.
Best Guac plan: 20 GB standard ($12.60 - $21.42) or unlimited with 2-3 GB/day quota.
You don't need a VPN in your eSIM.
Saily's biggest differentiator is the security features bundled into their eSIM: a virtual location tool, an ad blocker, and web protection. These come from their NordVPN heritage. Here's the thing: you're buying travel data, not a cybersecurity suite.
Saily's ad blocker claims to save up to 28% on data usage. That sounds impressive until you realize that even with a 28% data savings, Saily's effective price per GB is still significantly higher than Guac's actual price per GB. You'd save more money just buying a cheaper plan.
If you actually need a VPN for security on public Wi-Fi, get a proper VPN subscription. NordVPN itself costs about $3-4/month. The money you save switching from Saily to Guac would more than cover it, and you'd have a full-featured VPN instead of a lightweight proxy baked into your eSIM.
Saily's security features are nice to have. They're not worth paying double for your travel data.

Feature
Honest recommendation.
We're not going to pretend Guac is better for everyone. Here's when each makes sense.
Choose Guac if you:
- Want to pay roughly half the price for the same travel data
- Want transparent unlimited plans where you choose your own daily quota
- Need plans longer than 30 days (Guac offers 15, 90, and 180 day options)
- Want to buy your eSIM months before your trip (180-day pre-purchase window)
- Want cashback on every purchase without subscribing to anything
- Need to share eSIMs with travel companions
- Prefer one-time purchases with zero auto-renew risk
- Need large data plans (up to 50 GB standard)
Consider Saily if you:
- Want built-in VPN, ad blocker, and web protection bundled with your eSIM
- Value the NordVPN brand name behind the product
- Want the Saily Ultra all-in-one subscription (unlimited global data + NordVPN + NordPass + NordLocker)
A note about eSIM "reviews" online.
We have an affiliate program. So does Saily. So does almost every eSIM brand. Bloggers and reviewers earn commissions on every sale they drive, which is why almost every Saily review you'll find online includes a unique discount code. Some of those reviews are honest. But when every result on the first page ends with a discount code, it's worth considering the incentive structure. We'd rather let the price comparison tables above make our case. Compare the numbers and decide for yourself.

Frequently asked questions
For most travelers, yes. Both offer data-only eSIM plans in 200+ destinations. Guac is 42-65% cheaper at comparable plan sizes, offers more plan durations (including 15, 90, and 180-day options), gives 5% cashback on every purchase, and lets you choose your own daily high-speed quota on unlimited plans. Saily adds VPN and ad-blocking features, which may matter if you don't already have a VPN subscription.
Not exactly. Saily uses 1Global (a Netherlands-based wholesale carrier) and Guac uses eSIM Access powered by RedteaGO (a Qualcomm-backed, GSMA-certified eSIM platform serving 300M+ users). Both connect to major local carriers (T-Mobile, Vodafone, AT&T, Orange, etc.) in each destination country. The end-user experience is comparable. The difference is in the pricing and platform.
On standard (fixed GB) plans, no. On unlimited plans, Saily caps high-speed data at 5 GB per day, after which speeds drop to 1 Mbps. Their global "unlimited" plans have a 30 GB total high-speed allowance. These caps are not prominently disclosed at purchase. Guac's unlimited plans let you choose your own daily quota upfront.
Guac doesn't carry the overhead of a large cybersecurity company, a massive affiliate marketing program, or bundled VPN features. Lower operating costs mean lower prices for the same travel data.
Yes. Guac eSIMs are valid for 180 days before activation. Your plan only starts when you connect at your destination. Saily auto-activates after 30 days whether you've traveled or not.
Yes. Guac offers unlimited plans where you choose your daily high-speed quota (500 MB to 10 GB/day). After the quota resets every 24 hours. Unlike Saily, the quota is clearly shown before purchase.
No. Guac focuses on one thing: affordable travel data. If you need a VPN, the money you save with Guac vs Saily can easily cover a standalone VPN subscription, and you'll get a better VPN than the lightweight proxy Saily bundles in.
Yes, with no restrictions. All your purchased data or your full daily unlimited quota can be shared via hotspot to any device.
