Smarty's mobile broadband SIMs are designed for use in a router or MiFi device rather than a phone, running over Three's network to provide internet access without a fixed line. This suits situations where a fixed line isn't available, or as a flexible backup connection.
1. Who this suits
- Renters in short-term accommodation where fixed broadband isn't practical.
- Anyone needing a backup connection during a home broadband outage.
- Rural households without strong fixed broadband options but decent mobile coverage.
2. Data allowance matters most
Since a mobile broadband SIM is often the sole connection for a household, compare Smarty's data allowances against your expected usage across multiple devices, factoring in streaming and video calls specifically rather than typical single-phone usage.
3. Smarty's rolling, no-commitment model
Smarty is generally known for flexible, rolling plans without a long-term contract, which extends naturally to its mobile broadband SIMs — useful if you only need the connection for a defined period, such as a short-term let.
4. Comparing against a fixed broadband line
If a fixed line is available at your address, it will generally offer better value and more consistent speeds for ongoing heavy use — compare our broadband deals if this is an option.
5. Comparing against other mobile broadband SIMs
Compare Smarty against other mobile broadband options such as Vodafone and Mozillion for data allowance, network and price.
