That depends on which network your on. If it's t-mobile US then it will. It will not work on ATT (there are some areas where it might but as ATT upgrades their network those will begin to go away) or Verizon or Sprint. However it should work on most European and Middle Eastern networks depending on the tarrif you sign up for.

If you have T-mobile yes This model (C6833). Att no only H+ if you want 4glte with Att you need the model c6866 or the Google play addition.

It depends. 4G bands is a little bit confusing. There are so many in the world. This phone have most of then but NOT the 700mhz. the complete bands are belowC6833: 800/850/900/1700/1800/1900/2100/2600.The numbers of the bands on the Z Ultra (C6833) are 1, 2, 3, 4, 5, 7, 8 and 20. The big additions here are 2 and 4 which will open up the Z Ultra for broad use on major LTE networks in North America. AT&T; have band 17, Verizon use band 13, Sprint use 25/27 and US Cellular operate on 12. Only T-Mobile have stayed `open' on band 4. The other main carriers mentioned do also use bands 2 & 4, the unique bands allow them to lock down devices they sell to their own LTE networks, but 2 and 4 are open too.

I have simple mobile and when I had this phone the 3g did not work. It is not capable of 4g at all. I do not recommend this phone. It broke within a year of use.

I don't think so. I bought this as a backup device in case my primary phone fails, so I had to turn it on to check. In settings, I checked the network information and all it referenced was 3G. No mention of 4G. Hope this helps.

I don't think it's 4G but it will work with Almost all service plans that use a sim card

Yes, it is factory unlocked and suitable for many GSM providers (see radio bands). It is not 4G. It is HSPDA - which it will work on 3G speed
2184323
Yes! In fact, it is a 4G phone. Also, your service depends on what provider you use for this phone.

Hi Vicki, I have a 3g microcell and it works ok on my 4g phone (If you have high speed internet service and it is wireless you may have some trouble. But for the most part it works.

One more thing... Not sure that 4g will meet your needs... I purchased 32g version.

It does, but they cannot guarantee 4G. I do not have any issues with not having 4G...it is a tiny bit slower, but I don't have an issue with it.

Hi Stefano, this unit does not have a 3G or 4G feature. It might be on some other models, but on our end on the Helix models, we do not carry the ones with a 3G or 4G feature. Thanks, PCrush

Hello there,Not sure what is your question, but it is a very good cell phone and yes it is 4G..

Yes it is compatible with 4g but you have to get a SIM card first. I had the iPhone 4 as well and had to get it replaced
