Hi friends. I would like to tell you all that samsung galaxy j2 mobile is one of the bet mobile I have ever used. The moment when jio sims came into market I heard that jio sims are gonna work only in 4g handsets. The cost of 4g handsets was too more. Then I got to know about samsung galaxy j2 which is a 4g handset. The specification of this cell phone is best. It has duo sim option and a slot for memory card. Allover its a best handset. If anyone wants to buy cell phone then I would like to suggest to buy samsung galaxy j2.
