If your handset supports all active frequencies that is great news, but you still need to work through the rest of the list of things to look into. Also, if you know anyone local with an unlocked 900F S5 phone, try your SIM in their phone.

Specs for Israeli 900F and Canadian 900W8, differences in bold.
You need to confirm that your carrier does not use the missing frequencies i.e. B8 (3G GSM 900) & B20 (LTE 800)

SM-G900F
2G GSM B8 (GSM 850MHz), B10 (E-GSM 900MHz), B13 (DCS 1800MHz), B14 (PCS 1900MHz)
3G UMTS B1 (IMT 2100MHz), B2 (PCS 1900MHz), B5 (US 850MHz Cellular), B8 (GSM 900MHz)
4G LTE B1(2100), B2(1900), B3(1800), B5(850), B7(2600), B8(900), B20(800)

SM-G900W8
2G GSM B8 (GSM 850 MHz), B10 (E-GSM 900 MHz), B13 (DCS 1800 MHz), B14 (PCS 1900 MHz)
3G UMTS B1 (IMT 2100 MHz), B2 (PCS 1900 MHz), B4 (AWS), B5 (US 850 MHz Cellular)
4G LTE B1 (2100), B2 (1900), B3 (1800), B4 (AWS), B5 (850), B7 (2600), B8 (900), B17 (700)

OP this may sound ridiculous but go into your System>About Phone and check for your imei... you can also do *#06# hit send on your dial pad...

If your imei shows 000 or something weird other than the one that is printed on the sticker under the battery or box then you have a defective phone. I usually see this Unregister Network thing happen to quite a few Samsungs over the years, starting with the S2. You may have done something and caused the IMEI to get lost/wiped in the EFS.

The best thing to do in this case is you have to have the IMEI rewritten. This may be really easy if there is still an EFS backup on the phone or if it is still accessible. Otherwise at the time of writing this I think both the Octopus/Z3X cannot write IMEI on the S5 so taking it to repair shop can be pointless until it does.

Worse case scenario is your actual baseband chip is screwed.

Anyway, check to see if your imei is there. No IMEI = network cannot register you on as you device doesn't exist.

In isreal:

2G GSM: B8 (GSM 850MHz), B10 (E-GSM 900MHz), B13 (DCS 1800MHz).
3G UMTS: B1 (IMT 2100MHz), B5 (US 850MHz Cellular), B8 (GSM 900MHz)
4G LTE: B3(1800), Soon will use 2600Mhz too B7(2600) .

4g- Only before few week 4G open, but only 5Mhz of 1800Mhz are in use for now.


So only 900Mhz in 3G are missing..(Not all carroir useing this Fq...)
