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.

Great, that means it will work perfectly in Vietnam: Viettel’s Mobile Network Bands Technology Bands / Frequencies 4G / LTE B1 (2100 MHz), B3 (1800 MHz), B8 (900 MHz) In addition, some sources list B7 (2600 MHz) (used in dense urban areas). 3G / UMTS / WCDMA B1 (2100 MHz) and B2 (1900 MHz) 2G / GSM / EDGE B3 (1800 MHz) and B8 (900 MHz) Thanks.

Yes, you can use the device in Indonesia (Bali) with a 4G SIM from Telkomsel or Indosat, as long as the SIM card covers the 4G/LTE frequencies supported by the router. The router supports 4G/LTE frequencies such as 800/900/1800/2100/2600 MHz, which are used by Telkomsel and Indosat in Indonesia. It is important that the SIM card has a local data pack and is technically compatible. Roaming can be switched off if required.

The device works in Egypt with an Egyptian SIM card, provided the SIM card corresponds to the 4G/LTE network types supported by the router. The router supports 4G LTE with up to 150 Mbps download speed and is designed for worldwide use, including Egypt. It is important that the SIM card comes from an Egyptian mobile network provider and works on the 4G network supported by the router.

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.

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.

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...
