Here are the answers to your questions in the order they were asked: Yes, Lukewarm, Nonsense.

Yes. No problem.

Hi, I actually use the tp link abroad. It's enough to buy a sim card of the country (prepay) with a data package and it's done. The speed depends on the capacity / speed / quality of reception of the network you will use. I don't watch hd video with this system abroad, it consumes too much data. I hope this helps!

Hello Unfortunately, we can't say exactly, as we source from different sources and the version can vary. As a rule, however, it is the latest one. Greetings

No it can't be added to existing wlan. You need a sin card 4g

The problem has finally been solved. Salt has set up a "Salt Prepaid 15" subscription for me, which does not allow surfing at Fr2/day. After many hours of tech support/discussion, I was switched to "Salt Prepay", and now it works.

Yes, with the tpMiFi app you can send and read text messages via the router SIM. You need to connect your device to the router's Wi-Fi, open the app and log in with the administration password. You can then send new messages or check your inbox in the "SMS" section.

The device can function without a battery in power connection mode as it has a micro USB port that can be used for the power supply. If the device is used for continuous operation, it will remain switched on as long as it is supplied with power. There is no indication that the device will switch off automatically when connected to a power source unless it is switched off manually or the power supply is interrupted.

no

Seems to be a support case and not a product issue. Would have a look here: https://www.tp-link.com/de/support/download/m7350/ Otherwise, reset the device: Method 1: Hard reset/by pressing the RESET button Step 1: Make sure the device is switched on; if not, long press the power button and wait for it to switch on.

A SIM card from GoMo can work in the TP-Link M7350 Mobile 4G/LTE WLAN router, provided that the SIM card supports the same frequencies and network standards as the router. - The TP-Link M7350 supports 4G/LTE frequencies such as FDD-LTE Cat4 (800/900/1800/2100/2600MHz) and 3G/2G networks. - It is important that the GoMo SIM card supports these frequencies and network standards. If the SIM card is technically compatible, no problems should occur. However, it is advisable to check the specifications of the GoMo SIM card before use and ensure that there are no network or roaming restrictions that could affect the connection.

The original battery is currently not available in our range. However, this compatible battery that we offer is a reliable alternative and fully functional for your device.

Sì

e.g. at Digitec :-) https://www.digitec.ch/de/search?filter=pt%3D1984%2C18536%3D332404%7C1736559%7C899966%7C336692%2C18092%3D332376&is=sim&q=sim%20karte

The M7350 supports WPS: https://www.tp-link.com/us/user-guides/m7350_v6.2/chapter-2-set-up-internet-connection#ug-sub-title-1 This should therefore be possible. The performance of the M7350 is low. Using a repeater may help, but don't expect miracles. In your case, it may be more sensible to look for a better solution (e.g. FRITZ!Box 6820 LTE in combination with a Fritz repeater).

Yes should work with any (data) SIM card.

I've looked it up a bit, but I can't get it to work either. The official TP-Link website states that it only supports 2.4 Ghz: https://www.tp-link.com/de/home-networking/mifi/m7350/#specifications However, the manual for this device states that it can be customised: https://static.tp-link.com/res/down/doc/M7350(UN)_V3_UG.pdf However, this is a manual for an older version. My guess is that this function has been removed from the new iterations of TP-Link M3750. Hardware and/or software wise. I have adjusted the specifications at Digitec.

via the integrated web server.

This is a wifi router that allows internet access abroad if a SIM card is inserted. For Google Maps abroad, we recommend downloading offline maps.

Yes, I've already used it again in 2023 in the USA and Canada and I wasn't in a big city. However the network was not incredible. Currently the USA are offered by Swiss operators at less prohibitive and the pocket wifi has less reason to be.

I haven't discovered anything like this yet...

I can't really answer that because I don't know the conditions and standards in Afghanistan. Therefore, I can only assume: I receive Lte via the German Telekom network in the EU. Here, the device works perfectly as a hotspot. If other smartphones produced for Europe work in Aganistan, this device should also work. It depends on the mobile phone infrastructure, whether it is still western and whether it can still function or is maintained in the current situation. Unfortunately, it is a difficult question, but I hope that my statement will help a bit. ...

yes without hesitation

In short: The TP-Link M7350 will work in CH with all three providers. With LTE devices from the Far East, it is important to check the available band numbers. See CH LTE providers below. In vers. 8.0, the corresponding band numbers (in the correct order ...) were given in addition to the frequencies. Band 20 / 3 / 7 are offered by all three CH suppliers, Sunrise also offers band 8, and the other two band 1. TDD-LTE on band 38 is only offered by Swisscom.
