Smarty

Smarty is a UK budget carrier on Three's network offering eSIM with tethering at full speed on every plan, no throttling or hidden charges. You pay only for the data you actually use, and the mobile app tracks consumption in real time so there are no surprises. Their pricing is transparent and refreshingly simple, with no premium tier required to enable personal hotspot.

Smarty appeals to budget-conscious UK users and travelers who want tethering without paying extra or accepting slower speeds. Unlike carriers that reserve hotspot features for premium plans or throttle personal hotspot to secondary speeds, Smarty treats all data equally. It's most practical within the UK, though roaming is available in Europe where Three's partnerships keep costs reasonable for visitors.
