Worst Cellphone Network

I do not actually want to give one star, if Zero stars was possible that was the rating.

Even if all steps are followed to roam other networks, like they advised me to do, the network is terrible. Every Second call I make I get disconnected from the network for at least 10 mins. I struggle to get calls in, and clients always complain they cannot reach me, even after numerous times calling. They do not offer LTE for other smart devices on e-Sim like other networks. I wanted to cancel the contracts, but the retainer fee is so high that you cannot even do that. Worst decision I ever made for a cellphone network. The network department try to blame my device (Samsung S23 and Samsung Z4) but it did the same on Huawei as well, I changed devices because I believed them that it was a device error. They also do not want to hear when I say I experience in the whole country, not only where I live. I travel alot for work. Very frustrating!!!!
