A 30-day T-Mobile prepaid SIM aimed at travelers and short-term users who want unlimited talk and text plus unlimited 4G LTE data in the US. The biggest things to know are that it must be used in an unlocked GSM phone, hotspot use is limited (3G tethering), and data may slow after 50GB under a fair usage policy. Plan for activation, since it is not ready to use right out of the package.
The EIOTCLUB Data SIM Card for 360 Days is a data-only LTE SIM kit designed for unlocked IoT devices like 4G trail and security cameras, routers, and similar cellular hardware in the U.S. It’s intended to work with AT&T and T-Mobile networks, supports three SIM sizes via a pre-cut kit, and is positioned as a no-contract, long-duration plan. The main thing to double-check before buying is network band compatibility and that your device supports the required APN settings (with a U.S. APN of america.bics).
A short-stay Japan data SIM for travelers who want easy setup and solid coverage on the Docomo network. It includes 10GB of high-speed 4G LTE for up to 15 days, then speeds drop to under 128 kbps for the remainder of the period. Best for travelers with compatible unlocked devices, and especially for those who want hotspot tethering.
A budget-friendly prepaid SIM plan built for unlocked 4G/5G phones, offering unlimited talk and text plus 3GB of LTE/5G data on a 30-day cycle. It can be a solid fit for light data users, but activation and auto-renew management can be a pain point for some shoppers.
This preloaded Orange travel SIM is designed for trips across a long list of European destinations, offering 20GB of 4G data plus unlimited calls and SMS within Europe, with additional allowances for calls and texts to the rest of the world. The main tradeoff is that voice and messaging depend on the SIM working cleanly with your phone model and your device truly being unlocked, and some buyers report occasional setup or country-side prompting quirks.
The SpeedTalk Mobile Pre-Paid eSIM and SIM Card Starter Kit is designed for shoppers who want prepaid-style wireless service without a long-term contract. It supports both a 3-in-1 physical SIM and eSIM activation (on compatible iPhone, Pixel, and select Samsung models), with an unlimited talk and text plan that includes 11 GB of high-speed data each month before speeds reduce. The main caveat is that online activation and number porting can take time, and there can be plan-use confusion for some customers if they are not watching data usage closely.
The SpeedTalk Mobile SIM Card Starter Kit is a 3-in-1 (standard, micro, nano) physical SIM plus an activation path for eSIM on compatible iPhone, Google Pixel, and Samsung phones. It is aimed at prepaid, month-to-month use on unlocked devices with U.S. 5G/4G LTE coverage, including phones, hotspots, GPS trackers, and other IoT devices. The main catch: the experience depends heavily on whether your specific device and use case are compatible with the plan and activation process.
The Straight Talk BYOP CDMA 3-in-1 SIM kit is designed to activate eligible Verizon-compatible CDMA phones on Straight Talk prepaid service. It includes a triple-cut SIM (micro, nano, standard) for easier fit, but it will not work on GSM-based phones, so device compatibility is the biggest buying caveat.
The Orange Holiday Europe Prepaid SIM is a plug-and-play option for travelers who need 20GB of mobile data across many European countries, with hotspot (data tethering) and roaming calls/texts from Europe. The main caveat is that reliability can vary by destination and your phone setup, and the plan is tied to a 30-day credit window after first use (with optional registration for longer use).
This $5 preloaded SIM kit is designed for kids GSM GPS and activity-tracking smart watches in the US, pairing a 30-day service plan (50 minutes, 100 texts, and 100MB) with a selectable US phone number at activation. The biggest buying caveat is coverage and watch compatibility, since activation can fail if service is not available in your area or if the watch does not support the required cellular profile.
The Verizon Prepaid BYOP SIM Kit is a 3-in-1 SIM card (Standard/Micro/Nano) designed to activate an unlocked, compatible phone on Verizon’s Prepaid network with no contracts or credit checks. The main buying caveat is that keeping your number can take longer and may be sensitive to the timing of your current carrier’s release.
The KiwiSIM USA Data SIM Card gives you 12GB of data over 180 days on 4G LTE, built for unlocked devices that need mobile internet without calls or texts. It can automatically choose among AT&T, T-Mobile, and Verizon, but setup requires correct APN configuration and it may affect location-based streaming.
A Mainland China-focused 5G physical SIM from China Unicom, bundled with 20GB of data plus 300 minutes of talk and 300 domestic texts. Best for travelers who want a real Chinese phone number for common apps and services, with the main caveat that activation requires step-by-step setup and passport verification, and the SIM is Mainland China use only.
A prepaid Orange Europe SIM built for travelers who want reliable 4G/5G data and simple in-region calling for about a month. It supports tethering and hotspot use, includes a French phone number, and skips registration, but it is only for unlocked phones and requires roaming to be enabled.
EIOTCLUB’s triple-play 5G/4G LTE data SIM is designed for US-based IoT devices, especially security and trail cameras. It supports multiple nationwide networks and is positioned as no-contract and plug-and-play, but buyer success depends heavily on device band compatibility and choosing the right plan for your data needs.
This T-Mobile prepaid SIM is built for new activations who want unlimited talk and text in the U.S. plus unlimited high-speed data on T-Mobile’s LTE network for 30 days, with additional 5GB data available in Canada and Mexico. The main catch is that it must be activated through the seller (it will not work before activation) and it is not a refill or number-transfer option.
The Puffin Smart Data Only SIM Card is designed for unlocked 4G/5G devices that need cellular connectivity without voice service, making it a practical fit for security cameras, hotspots, dashcams, and GPS trackers. It uses both AT&T and T-Mobile networks and can switch between them when one is weak, but you will need to activate it and choose a data plan (the SIM does not come with preloaded data).
The Boost Mobile SIM Kit pairs a 3-in-1 SIM (plus optional eSIM activation) with a $25/month forever Unlimited plan that includes unlimited talk, text, and 30 GB of premium high-speed data. It’s a strong fit for budget-focused shoppers with an unlocked, US 4G+ phone, but activation can be fiddly and billing can vary if AutoPay or plan expectations are not aligned.
