Many reviewers point to low prices, a simple sign-up, and an app that’s easy to use. A large share of complaints focuses on unauthorised or repeat charges and disputes over cashback or rebate deals. Network speeds and call reliability differ widely by location.
Examples from available reviews (Dec 2021 – Feb 2026).
Reviewer loves Smarty, praising good service, price, and ease of use.

Many reviews mention unexpected monthly debits and cashback transactions being disputed. Several customers describe ongoing billing arguments and refund requests that were not resolved. A smaller group reports smooth activation and a straightforward setup.
A substantial group praises the low prices, rolling monthly contracts, and occasional discounts. Others say the cashback or rebate they expected was reduced or turned into charges. Positive feedback often ties value to basic, no-frills plans.
Many users describe quick SIM ordering and simple account management through the website or app. Multiple reviews mention login problems, difficulty cancelling, and long waits for ticket replies. Several highlight fast number transfers when support responds quickly.
Several reviewers report solid coverage and fast data where they live. A sizeable group reports weak reception, frequent dropouts, and slow speeds elsewhere, including roaming failures. Reviews also mention specific weak-signal situations such as motorhome use and repeated outages in Brighton.
Many complaints describe slow, repetitive customer-service exchanges and delayed ticket replies. Reviewers also mention PAC codes being held back, number transfers stuck in queues, and rebate processes being blocked. Some note clear messages about offers and no hidden costs.
Feedback splits between highly satisfied reviewers praising price and ease of use, and low ratings alleging unauthorised charges and weak support. There are multiple one-star accounts focused on money disputes alongside multiple five-star accounts reporting fault-free service. This gap points to very different outcomes for different customers.
