Emmy, try to turn WCDMA/GSM network mode on. I own this phone and I use UMTS/HSDPA high-speed internet. Also, if you own a dual-sim model, try to use SIM1 for 3G internet; SIM2 may have 2G only.
Through my experience with this model is very bad because Pick up the GSM network is very very weak and internal memory is not enough

Maybe the problem is SIM card who can not support 3G or 4g . Go to your mobile provider and ask for new SIM card with same phone number which support 4G network
