1. ByteSIM pricing and plans
ByteSIM offers eSIMs with global plans and pre-set durations, covering various countries. For the USA, they provide 5G unlimited data with unlimited calls and limited plans on T-Mobile, AT&T, and Verizon.
The pricing for one-day AT&T and Verizon data plans are structured as follows:
| Data plan | Price per day |
|---|---|
| 1 GB/day | $3.50 |
| 2 GB/day | $3.90 |
| 3 GB/day | $4.50 |
| Unlimited 5G Data | $4.90 |
ByteSIM supports multiple devices via hotspot tethering, though data usage limits may apply. Unlike traditional SIM cards, only the T-Mobile unlimited plan includes calling and SMS.
For instant activation, ByteSIM’s AT&T and Verizon eSIMs are delivered via email, but the T-Mobile plan requires manual installation and can take up to 24 hours to activate.
2. Network coverage and quality
ByteSIM offers global coverage in 200+ countries and regions, connecting to local carriers for reliable connectivity.
ByteSIM does offer 5G/4G/LTE data speeds, but certain plans require additional steps. For example, the USA Unlimited 5G Data plan has specific service time requirements from T-Mobile. After purchasing, users must:
- Fill out a form with the activation date (at least one day after purchase).
- Provide the IMEI and EID of their mobile phone.
- Contact the support team for urgent activations.
3. Customer service and technical support
ByteSIM offers 24/7 customer support via email and WhatsApp. Here’s how it performs on different platforms:
- App Store rating: ⭐ 2.8/5 from 5 reviews
- Google Play rating: ⭐ 3.4/5 from 86 reviews
We recommend you check reviews and ratings across various platforms, like Trustpilot, to get a deeper understanding of the customer service and support ByteSIM provides.
4. ByteSIM app
The ByteSIM app makes mobile connectivity simple. It allows users to:
✅ Browse global data packages and local data plans
✅ Track data usage in real-time
✅ Activate an eSIM card using a QR code
✅ Check device compatibility before purchase with the built-in compatibility checker
The app also supports hotspot tethering, letting users share their internet connection across multiple devices.
5. ByteSIM member program
ByteSIM offers competing price discounts for frequent users through its tiered membership program:
| Membership level | Discount | Spending required |
|---|---|---|
| Silver | 2% off | $100 |
| Gold | 8% off | $500 |
| Platinum | 15% off | $2,000 |
To become a member, you must sign up and accumulate spending over time. The discount applies automatically once a tier is reached.
However, if you only travel occasionally, you might not reach the Gold or Platinum levels quickly, making the benefits less accessible for casual users.
In addition to the membership program, ByteSIM offers an affiliate program where users can refer others and earn a commission.
Affiliates receive 10% of the sale amount for every successful referral. The program works on a last-click credit policy with a 30-day referral window.
Other eSIM providers take a more flexible approach. For example, with Holafly’s Travel Club (HTC), every purchase earns you 5% cashback in HolaCoins, which you can redeem for discounts on future orders.
Here’s what you need to know:
- 100 HolaCoins = €1 (approximately $1.05 USD) in discounts.
- HolaCoins can be redeemed at any time, and no minimum spending is required
- Cashback applies to all eSIM purchases
- You can refer friends and earn 500 HolaCoins for every new customer
Holafly rewards every purchase immediately, making discounts accessible to travelers who don’t frequently buy eSIMs in bulk.
Get Holafly’s unlimited data
If you’ve decided that ByteSIM is not for you, but you’re still looking to buy an eSIM, consider Holafly’s eSIMs instead.
With Holafly, you can customize your plan based on your travel duration from 1 to 90 days. Plus, you get unlimited data with no hidden caps or slowdowns.
