ByteSIM is a Hong Kong-based provider of prepaid travel eSIMs, offering mobile data along with calls and SMS in more than 200 countries. The company leans on affordability and convenience: customers scan a QR code to switch on high-speed 5G or 4G LTE data, removing the need for a physical SIM card. Plans come in several shapes, including daily options, large data bundles and unlimited alternatives, so a traveler can match a package to the length of a trip and the data it demands. Hotspot tethering is supported as well, which lets one connection serve other devices on the road.
Because ByteSIM works through local carriers, users can avoid roaming fees while staying connected in popular destinations across Asia, North America and elsewhere. The model behind this is simple enough: a travel eSIM is a downloadable profile that lets a phone join local networks abroad, so coverage and speeds rest on the carriers a provider partners with rather than on the traveler's home operator.
Payment can be made with PayPal, Google Pay or Apple Pay. Refunds come through when an eSIM malfunctions because of ByteSIM or its provider, or when it cannot establish or hold an internet connection, and the money is returned to the original payment method or issued as store credit. A tiered membership program offers savings of up to 15% depending on spending, and members collect points for registering and for purchases, with 20 points worth $1 off.
Codes go into the promo code box at the ByteSIM checkout; deals need no code.
Pick a code from the list above. Its details give the discount and any conditions, such as a minimum spend or an end date.
Select Show Code. A window opens with the full code, a Copy code button and a link to bytesim.com.
Add your items at bytesim.com, then paste the code into the promo code box in your cart or at checkout.
Make sure the discount shows in the order total before you pay. If it does not, the order may not meet one of the code's conditions.
ByteSIM does not have a referral code for discounts at the moment. The store does run assorted promotions and deals on its website, so it is worth checking for those when shopping.
ByteSIM sells gift cards for prepaid SIM card funds, starting at $60. These cards work across major networks for travelers and can be picked up on Wednesdays near college campuses.
The ByteSIM app is aimed at travelers who want both convenience and savings. Booking through it is straightforward, and it gives users access to deals and discounts available only in the app, whether that means a discounted flight or special offers on roaming services, so there is extra money to be saved.
Signing up for the ByteSIM newsletter gives travelers a route to savings. Subscribers receive exclusive deals and seasonal promotions built around international travel needs, and keeping up with those offers lets them catch discounted airfares and hotel stays.
A code fails when the order misses one of its conditions, such as eligible products or a minimum spend, or when the promotion has ended. Each offer's details list its conditions.
