A man on Nairaland forum posted how his tecno phones didn’t work in USA with proof of a screenshot.
Here is what he posted below:
“I use a Tecno Camon 9 Phone but presently I am unable to use this phone in the USA. I got the mobile phone from Nigeria where it worked perfectly with my cellular lines.
“The SIM CARD networks (MTN and GLO) where expected to roam here either to T-MOBILE or AT & T, unfortunately it didnt roam to any of these lines. I tried using other cellular network SIM CARDS on the mobile, but the issue still persist even when I tried manually searching for network, it says NO NETWORK AVAILABLE (as shown in attached).
“The phone doesn’t have a GSM network, all I can find is 2G to 4G. Kindly assist to help on any possible way I can unlock or resolve this issue. My wife also encounters the same issue with her Tecno Phone W5.”
Solution 1: Roaming with your MTN and Glo line while travelling abroad will ensure you are always reachable even if you are thousands of miles away from home.
Two mobile phone network operators in different countries enter into a contract called a roaming agreement. This makes them ‘roaming partners’ so, for example, MTN Nigeria customers can make and receive calls, send and receive SMS, browse the internet, send and receive emails or any other service when applicable, in the UK using Vodafone. Vodafone UK customers can do the same in Nigeria.
As an MTN or Glo customer using either a prepaid or postpaid line, your phone is already set up to be used abroad. Roaming service is available by default on your MTN line. There is no monthly fee, no connection fee and no deposit required before you can roam. However, the cost for making and receiving voice calls or sending SMS while roaming abroad depends on the country you are visiting.
Solution 2: It might also be a frequency issue. The phone is made for Nigerian frequency of 900/1800 MHz spectrum while in the US, they use 850 MHZ and 1900 MHZ in Canada.
