I buy this set for using Relince 4g. I parches this set with 4g sim card with Relince JIO center. Its internal memory 16 GB.
This phone supported OTG. I use pen drive also. I use this set before 1.5 years. With in two month from purchasing date its flash light burn. But service center replace tis with in free cost. This product 1 year warranty with 2 years extended warranty. Total three years warranty. This set is not too first. Its sound is low. I think this is chip and good set for using reline 4g use.
