S21 5g unlocked ineligible on any network

[userQzLGjZNKDE]

i have delivered 2x S21 ultra 5g unlocked devices. i have been trying for 2 days to add these phones to my current carrier and they are "ineligible based on imei". i have tried verizon, t-mobile, google fi, etc. and all ineligible.

what is going on here. i was shipped these 2 days ago and cannot use them?  is this because the IMEIs have not been released yet?

or are these devices "bad" and i will need replacements?

@Adv360 hey there! So sorry to hear you're having some problems. Have you contacted your carrier regarding your mobile network issue by chance?

I have issues too: https://us.community.samsung.com/t5/Galaxy-S21/S21-Ultra-5G-Issues/td-p/1676443

As well as other users on Reddit: https://www.reddit.com/r/tmobile/comments/l7idnv/mobile_data_not_working_on_s21_ultra/

For me it's the 5g band that makes it not connect. If you go into mobile netwrks and coose LTE (non 5g one) it connects.

yes we switched out the Sim card, reset the mobile network, factory reset the phone. I spent like 2hrs at the store trying to fix it and even tech support couldn't resolve it.

Sent that puppy back for a free replacement...Don't wait for software,it might not be a wide spread issue..

Please speak with your carrier regarding issues using their services.

There is a post on Reddit already, but wanted to start one here. I am having issues with my T-Mobile S21 Ultra and 5G. I've been home for 2 days since getting it (pandemic and all) went for a walk this morning and could not connect to anything. Tried various things, until I found turning 5G off got me connected. Looked online and saw others were havin this issue and some had success changing the APN Protocol setting from IPv6 to IPv4/IPv6. Well that kind of worked for me, it connects, but slowly and with pockets of no data still happening. 

I compared my new TMo S21 Ultra to an unlocked Verizon S20+, and it was astoundingly bad (same SIM on both phones):

5G Speeds S21 Utra test 1 - Ping:9999, DL: 3.22 Mbps, UL: .08 Mbps

5G Speeds S21 Utra test 2 - Ping:449, DL: 12.36 Mbps, UL: .16 Mbps

4G Speeds S21 Utra test 1 - Ping:62, DL: 11.24 Mbps, UL: .05 Mbps

5G Speeds S20+ test 1 - Ping:18, DL: 27.8 Mbps, UL: 4.12 Mbps

5G Speeds S20+ test 2 - Ping:20, DL: 38.3 Mbps, UL: 2.18 Mbps

Something is not right here
