KiwiSIM

What KiwiSIM is

KiwiSIM sells physical data-only SIM cards and eSIM profiles for travellers, as well as mobile hotspot routers and security cameras. The company is positioned as a retailer with quick shipping and flexible top-up options. Customer support is available via email with a stated response time of within one hour, and the site displays an affiliate program offering 10 percent commission on referrals.

Plan options and pricing

KiwiSIM's core USA offering is a 4G LTE SIM card designed for unlocked phones and IoT devices. Two main options are advertised as bestsellers and on sale. The first is a 6GB plan valid for 90 days, priced at $18.99 USD (regular price $29.98, a 37 percent discount). The second USA option is a 10GB plan for 60 days at $28.00 USD (regular price $59.99, a 53 percent discount). Both cards support AT&T, T-Mobile, and Verizon networks. The site does not specify which carrier the SIM will automatically select, only that compatibility exists across all three; a customer's phone may default to one network based on signal strength and availability, but manual carrier selection is not mentioned as an option. For device types like dash cams and IoT routers, network selection is automatic and not user-controllable, so flexibility is limited.

For longer trips or heavier data use, KiwiSIM markets a 12GB plan with 180-day validity at $26.99 USD (on sale from a regular price of $49.98, a 46 percent discount). This plan is marked "Best Seller," suggesting high demand, though the destination is not explicitly stated on the visible portion of the site. The 180-day validity is the longest KiwiSIM advertises; for travellers staying abroad for six months or more, this product covers a full half-year window and can be recharged if needed. The eSIM option for "USA/Europe" is advertised starting from $4.99 USD, the lowest entry price KiwiSIM offers. Customers can choose a plan during checkout when selecting eSIM, and the final price will depend on the data and duration selected.

All physical SIM cards are sold with a "Plug and Play" ethos, insert, configure device settings, connect. Top-ups are available; customers can purchase additional data once their plan is active, extending coverage mid-trip or adding more gigabytes. The website allows customers to log in and check remaining balance, track usage, and manage their data, a feature useful for multi-week trips where data consumption needs monitoring.

Coverage and networks

KiwiSIM states "seamless coverage in 51 countries." The site does not enumerate these destinations on the homepage, nor does it explain which local carriers operate the SIM in each location. A customer planning travel outside the USA must navigate to the destination pages or contact support to confirm coverage. For USA cards, the network support is explicit and generous: AT&T (the largest US network), T-Mobile (the second-largest), and Verizon (the third-largest), covering the overwhelming majority of US landmass and population. For the international eSIM, the destination list is not visible in the captured page; only the price range ($4.99+) appears.

The company also sells a 4G LTE portable WiFi router (300Mbps, CAT4) with a built-in SIM card slot, supporting AT&T and T-Mobile networks, paired with a data SIM card for $69.99 USD and up. CAT4 is an older LTE category (LTE-A is newer, 5G is newer still), so the router is optimized for reliability on established LTE networks rather than peak speed. The 300Mbps WiFi is the device's wireless transmit speed to connected clients; the actual data throughput depends on the cellular network's speed and the SIM's plan limits. This product appeals to travellers who need WiFi for multiple devices (families, small groups, or multidevice users) without relying on public WiFi security risks. The router's $69.99+ price point is significantly higher than a SIM card alone but competitive for dedicated hotspot hardware in the travel market.

Practical details

All KiwiSIM SIM cards are data-only; no voice or SMS capability is described. The product is designed for unlocked 4G-compatible devices, including phones, tablets, routers, IoT devices, and dash cams (the site specifically cites 70Mai 4G dash cams as working customers in one review). Installation requires two steps: insert the SIM card physically (for physical SIMs) or scan a QR code (for eSIMs), then enable roaming and set the APN (Access Point Name) in device settings. The APN varies by plan and is provided by KiwiSIM at purchase or on the website; common values like "PLUS" and "Automatic" appear in reviews. Customer reviews note that this activation step is straightforward once the user has the correct APN, though one reviewer described initial confusion around finding and entering the APN, a common pain point with physical SIMs compared to eSIMs. Once roaming is enabled and the APN is set, the SIM connects automatically to available networks.

Customers can check their remaining data balance by logging into their KiwiSIM account on the website; the portal displays usage and remaining gigabytes, a useful feature for customers uncertain about how much they've consumed. Device compatibility is listed on the site (verified link mentioned in captured text as "Compatibilidad"); the site notes that "iPhone, Samsung, Pixel and many more" are supported. The list is not exhaustive, and the company recommends checking that the device is 4G-compatible and unlocked. For customers with older phones or carrier-locked devices, this can be a barrier; an unlocking service or older-phone compatibility information would improve accessibility.

An eSIM can be transferred to a different device once after purchase; reinstalling it on the original device is not possible after the transfer, a security measure to prevent duplicate activations. For physical SIM cards, no transfer is mentioned, implying they are locked to the first device once activated. If a customer's SIM fails to activate, support can troubleshoot via email and typically responds with multiple detailed steps within one hour. Customer reviews praise this support quality, noting that it resolves issues that would otherwise ruin a trip. The email-only support (no phone line mentioned) is slower than WhatsApp or live chat but represents a real commitment to helping customers get connected.

What KiwiSIM does not settle

The homepage does not specify which carrier the USA SIMs will connect to (whether the device will select one of the three supported networks automatically, or if the choice is manual). The 12GB 180-day plan's primary destination and coverage zone is unlabelled on the homepage. Throttle speeds after data is exhausted, or whether "unlimited" refers to any of the plans, are not published. Monthly or per-request subscription management options are not mentioned; the product is framed as prepaid. Refund eligibility and whether unused plans are refundable are not addressed on the visible page.

KiwiSIM suits travellers who are comfortable with SIM card installation and APN configuration, want flexibility with multiple carriers in the USA, and prefer the simplicity of a pre-loaded card that requires no app or eSIM setup. However, anyone needing voice calls or SMS through the SIM, or who wants a step-by-step guided setup, would be better served elsewhere.
