I am looking for all the Carrier Aggregation combinations this phone support. I am in India and have DS model and my service operator here Reliance Jio support 3CA (Band 3+5+40) combination but I am only getting 2 CA (Band 3+5)
Does this phone support 3CA? if yes band 3+5+40 CA available in DS model?
Any kind soul please remove my doubts because I am seeking this information for many days.
Thank you.
No one knows?
Hi., In India there's very low awareness about LTE CA. Only in major cities Jio seems to have enabled it. Hence if you care about this more, buy OP5/5T that surely support 3CA...

hi friends I bought an axon 7 on amazon, the model number is a2017u.
I checked with sims from 2 major carriers in my country and first issue is frequently I am getting no service warning and literally I cannot use the phone for call and sms for daily use. Throughout the day it mostly says no service.
Next issue is phone is not support 3g band and it should as the spec says. Will explain later on this post please keep read on.
before I purchasing I asked clearly on amazon answers whether this support in my country, sri lanka the answers were yes it should work in my country.
And also, I have checked the frequency bands in my country and the model above whether they are compatible each other.
Supported bands by the phone model a2017u as official ZTE site mentioned are: (check the specification section in
• GSM/EDGE:B2/3/5/8
• CDMA BC0/1/10
• UMTS/HSPA: B2/B5/B4/B1/B8
• LTE: B2/B4/B5/B12/B13/B17/B7/B3/B1/B20/B29/B30/B25/B26/B41
• 2CA: B2+B4, B2/4+B12, B2/4+B29, B2/4+B5, B41+B41, B25+B25
In gsm arena also here are the bands support by usa model above
• 2G bands - CDMA 800 / 1900 - USA
• 3G bands - HSDPA 850 / 900 / 1700(AWS) / 1900 / 2100 - A2017G, USA
• 4G bands - LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 12(700), 13(700), 17(700), 20(800), 25(1900), 26(850), 29(700), 30(2300), 41(2500) – USA
In sri lanka support bands are
• 2G capabilities - GSM 900, GSM 1800
• 3G capabilities - UMTS 2100
• 4G capabilities - LTE 1800
With all the above verified information, can some of you who actually familiar with these technical stuff, confirm this phone should work in my country?
Because when I contacted official zteusa online chat they say my country may not support even I clearly explain that if the band is support it should work but they are not very supportive and they end up saying the same thing again and again.
I spent over more than 400 usd for the phone with shipping and clearance and everything and now I cannot use the phone for my daily use. And on the otherside zte support team is not supportive while I am going with the facts.
Please some experts here help me how to solve this situation. The frequency bands doesnot depend on the country right ? if the same band 2100 support for 2 different countries then it should work like the same isn’t it ? not just for USA right ?
And “No Service” status of the sim that i am getting frequently almost every time also due to that frequency band thing or hardware defect of the phone ? any thoughts ?
please clarify someone who know these stuffs well.
Please help friends I am really tired of this situation looking for answers. Sadly there is no official agent for zte brand in our country. So I am stuck here. With all the facts above phone should work in my country right?

No service warning: bad reception area or defective phone, you need to go close from any cellular tower and check there.
Is your phone in and out of 3g band?
Is your phone in and out LTE band?
Read above.
You do a great job searching for bands and carriers from your country, I bet for a defective device. Sorry

hi mate first of all thanks for the reply.
i checked 4g and its working but in my country there is no much coverage. so 3g is wt we have to use mainly here. and 3g band is not working. but specs says otherwise.
can you confirm if band support as an example 3g - 2100 band in here and USA then the phone should work in both countries without any issues right ?
and no service thing is appear most of the time in daily basis and time to time appear actual service provider name and signal bar but mostly saying no service. this cause the GSM band right ?
i dont have much technical knowledge in that area. thats why i need to confirm this mate. bz zteusa site support team seems like not taking the responsibility here. so i have to go with the confirmed facts u knw. thanks again for the support mate.

You can change sim card
Or:
do a full factory reset to the terminal
Stop asking for a magic trick, that's not going to happen.
This is simple: put another sim card, or do a full reset. It's a basic thing.
You choose the wrong phone if in your country the cellular signal is weak. Do you want an advice? Return the phone and ask for a refund.
Try to flash A2017G bootstack provided by DrakenFX

Hi,
Try to read more about 4g+ (where 2 ou more bands can be used at same time)...
Anyone tries to unlock the LTE (4G) Bands on z17 mini?

Reading now more about unlock in

But nobody has unblocked this frequency.
Well, soon as possible, I'll try and back here to post if worked.
Hi Friends,
Ever since I got hold of my Galaxy J5(J500F), which was imported from Saudi-Arabia to India, one thing bothers me a lot. That is, it didn't support the TDD-LTE band 40, whereas the Indian counterpart of SM-J500F does support it. Consequently, I'm unable to experience the true internet speed, while on one of the reputed Indian network operator servicing on LTE Band 40.
It's quite absurd that the both SM-J500F(Indian and Other regions) differ in terms of band capability, though they possess same hardware.
So, my humble request to great minds over here is, can you please tell me any tricks to enable the band40. Or, really is it possible to do so?
Thanks
I have ZB601KL device - 6GB I wold like to know that is the device support LTE 2CA ?
I do not get the 4G+ symbol, only 4G so I assume that carrier aggregation is not being supported in my present scenario. However, CA depends on the carrier, band and SoC (modem). SD636 with X12 LTE modem is CA capable and you can manually enable CA if you are BL unlocked+rooted.
Presently in Indian region I think Jio has deployed CA in Band 3+5 / 5+40 / 3+40 & also 3CA whereas Airtel has deployed CA in B3+B40 but it's 4G network is patchy and only available in some areas. Rest operators I don't know
I got 4G+ on my Nokia 7 Plus when using Airtel at the same time its doesn't on Max Pro
It has to be implemented by Asus like it has done on the ZB602KL variant.
Can any of the devs advice if the modem firmware of ZB602KL be flashed onto ZB601KL variant?
Hello everyone!
I live in Australia, and have just ordered this phone in India, who is supposed to bring it to Australia next week.
The box says 'Indian sim only'. But when I asked the Samsung customer care and looked into some other sources, people say that after using it on an Indian sim for 10-15 mins, it'll work on other networks too. The bands are supported though.
I'm really confused, whether to keep it or return it. Please suggest! Thanks in advance.
https://www.frequencycheck.com/carr...m-td-lte-128gb-samsung-m307/telstra-australia
I do not know how accurate is above information because from other source seems Telstra Au uses more frequencies
https://www.whistleout.com.au/Mobil...nJczYWP8cUPDqJ8YucWnA1Mnnxor8DGDNYbT-jiKyYepW
Supported bands from Sammobile
https://www.sammobile.com/samsung/galaxy-m30s/specs/#SM-M307F
From above seems following bands are supported:
900MHz (B8)
1800MHz (B3)
2100MHz (B1)
2600MHz (B7)
Thanks @pabgar for the info. I think the bands are supported. It's the regional lock I'm worried about. Because the box says Indian sim only. And there are confusing facts over the internet. Some say it won't work outside India, but others say that after using it on Indian sim and making a call for 10-15 minutes registers in on the Indian carrier, then it works on other networks too. Band compatibility:

I remember the Australians telling me Band 28 was necessary for good service within Australia.
Indeed B28 is low 700MHz band applied in rural areas because of long range from BTS
It works!
Happy to report that it works well on Telstra, and in Australia.
