phone not picking up on 4g

[jdcaddell]

OK i bought 4 razr's the other day for everyone in my family and we all travel to the city together allot. I have noticed that my phone when held next to the other 3 phones doesn't connect to the 4g for some time after the others do and it also loses it first. I was wondering if there was a problem with my phone or if there was something that i can do or need to do to get it to pick up on it like the rest of my phones.
