After witnessing several Nokia Asha phone launches in India, Samsung could take no more and hence Samsung launched low-cost dual-sim budget java based smart features phone in India under REX series/lineup. These phones will compete with Nokia Asha series and other low-cost phones. Samsung launched REX 60, REX 70, REX 80, REX 90 phones priced between Rs.4280-Rs.6,490 that are based on Java and feature Samsung Apps store for downloading apps. All these phones support dual-sim dual standby. The UI on these phones are that of Samsung android phones with Touchwhiz interface. These phones will not only compete with dual sim Nokia asha series, but also with similar low-cost dual sim android phones from Micromax, Karbonn, Lava, and other domestic brands.
