Very good phone wid 2 gb ram.fast speed, hd screen, screen size awesome battery backup lasts long but only problem I faced using Samsung E7 was I cannot use 2 sim cards at same time either u can use memory card or ypu can use 2nd sim dis is the only drawback I faced using this phone otherwise the phone is very and yes it is not 4g.
All phones nowadays are 4g enabled. This is the best phone one can get in budget with a brand like samsung which is a very trusted brand and has a very good service for its products
