How is reception to compare HUAWEI E5186 to iphone6

[snake811016]

Hi,all,i have reception of 3G with 8ta in my iphone6,LTE only appear in 3-5seconds sometims in my bathroom window(sometimes in room,),but 3G most of time,and my 60G+60G will expire in next month.I interesting at HUAWEI E5186 which is R999x24month(100G),i wonder,Does the HUAWEI get better reception than iphone6?
If not,i just rather go to Big20G(which is little less for me).could someone recommend better data deal?thanks very much!
