BV4900 - The Lowest-Cost Rugged Phone For Enterprise

An Entry-Level Android 10 Smartphone With IP68 and IP69K Certification

THE LOWEST-COSTING ENTRY LEVEL RUGGED PHONE

The BV4900 is a very low-cost rugged phone from Blackview. Although its a very capable entry-level rugged phone, it is not recommended for power users that demand high graphics gaming or video editing. This phone is more geared towards enterprise usage.

The BV4900 is a great communication and activity recording tool in the industrial and construction industry with dusty, wet, or harsh environments. It will run the Android apps well enough and the handset can last all day long with its 5580mAh beast of a battery. Perfect for team usage in the corporate world.

A very humble device for those that need a basic rugged smartphone. People that work in the construction or industrial field of work will be confident carrying this phone around, with peace of mind that it will not be easily shattered when dropped or hit by a hard object. The BV4900 is Military Standard CERTIFIED (MIL-STD-810G).
This can be also be a suitable entry phone for the children who can be very rough on handling electronics.

What USA buyers need to know

  1. All Blackview Phones are network unlocked. 
  2. Only SOME Blackview phones have the 3G and 4G bands to work in the USA. 
  3. HD Voice is required for phones as 2G and 3G networks are being retired.
  4. Not all carriers are welcoming on BYOD Phones. 

In short, we have tested BV4900 on AT&T and T-Mobile and have verified that the phone works great with these two major USA carriers. Verizon,however, only has a few frequency bands supported by this model so we do not recommend this carrier at the moment.

1. Blackview BV4900 is Unlocked

Compatibility to local carrier provider is 1# problem buyers face in buying foreign manufactured smartphones. This makes you can't buy every phone you want and expect it to work on USA Carriers. You should never buy a network locked Blackview set. They are also rare so this point should be easy to fulfil.

☑​ Blackview BV4900 is unlocked by default.

2. BV4900 has bands that work on AT&T and T-Mobile

Based on data in devicesranks, frequencycheck, & kimovil.com, Blackview BV4900 should work with most USA Carriers. BV4900 supports many bands' frequency.

BV4900 USA Version Bands:

- 2G GSM: B2/B5/
- 3G WCDMA: B1/B2/B4/B5/B8
- 4G FDD-LTE: B2/B4/B5/B7/B12/B17/B40; TDD-LTE: B41

Carriers can use many bands but there are only a few which is important. Please see the BOLD 4G LTE Bands.

Main bands for use in USA: 2,4,12,13,17,25,41, 66,71

As you can see in this bar chart, the vast majority of 4G LTE mobile data volume goes through mid-band spectrum. That would be the 1900MHz band 2 (B2) for AT&T; the 1900MHz B2 together with 1700MHz AWS bands B4 and B66 for Verizon; and pretty much the same combination of B2, B4 and B66 for T-Mobile.

Those bands make the backbone of 4G LTE network coverage especially for urban areas .In rural areas of the United States, the importance of low-band spectrum (below 1GHz) has a greater importance. Here, Verizon Wireless is particularly well invested with its 700MHz bands B13, B14, and B17. AT&T and T-Mobile, on the other hand, rely on 700MHz band B12.

☑​ Blackview BV4900 has all of the main bands used by Carriers in the USA

3. HD Voice is needed from 2022

Come 2022, 3G networks will be retired. This means that your Voice Calls must use the 4G network. Hence some carriers like AT&T and Verizon have stopped activating non HD Voice Phones. Most new phones should have HD voice and BV5900 has no problems getting HD Voice on AT&T and Verizon.

A simple test to see if your phone is HD Voice Capable is to

  1. See if there is a HD or VoLTE icon at the signal bar
  2. Make a phone call and see if your network connection stays on 4G. It should not drop to 3G
  3. While on a phone call, surf the internet.

If your phone can do all three, you most likely have a HD Voice Phone.

☑​ Blackview BV5900 has all HD Voice working on AT&T, Verizon & T-Mobile

4. Not all carriers are welcoming on BYOD

To activate your Blackview to mobile providers in United States such as AT&T, Boost Mobile, Cricket Wireless, FreedomPop, Google Project Fi, H2O Wireless, Lycamobile, Sprint, T-Mobile, Ting (GSM), U.S. Cellular, Verizon Wireless, MetroPCS, Mint Mobile, Straight Talk.

  1. Find your phone IMEI
  2. Register / call to your carrier mobile provider
  3. Then it will be activated

Here is a guide from AT&T: https://www.att.com/wireless/byod/

Sometimes carriers just won't activate your unlocked or BYOD phone. This is true if you do not have a BYOD plan or on some more restrictive carriers like Verizon/Sprint. In this case, feel free to use our 30 days refund/return policy.
