1- for setting of 4G, your phone should compatible with 4G network, either contact Etisalat Communications to change your sim to 3g network, so that you can use the same SIM and number.
For more about Setting of Mobile 3G/4G network just go to
Setting>>Under Wireless & Network >>> More>> Mobile Networks >>Network Mode>> select accordingly 3g, 2g, 4g OR all
please share more if you feel any issue
I have just read your review of the O+ smartphone, I purchased one during my last visit to Philippines in May of this year. I am currently working in Abu Dhabi, and unfortunately did not check that the phone worked correctly while I was in Philippines. I cannot connect to the 4G network here, is this because the phone is only 3G capable? I have a number of colleagues at work but nobody can find the mobile data selector in Settings. The Etisalat SIM card is working ok, I checked it in a Samsung smartphone. Hope you can help before I purchase another new phone, as I have just signed a 2 year post paid contract with Etisalat Communications.
On another subject, can you recommend a smartphone that does not have any camera installed, as cameras are not allowed at my place of work. ( I removed the camera from the O+).
Looking forward to your reply
