They raised the demand at a virtual press conference and sharing meeting on Monday organised by Cox's Bazar CSO NGO Forum (CCNF), an alliance of 60 local and national civil society and NGOs.
Journalists from both Cox's Bazar and Dhaka joined the online programme.
Nayeem Gowhar Warha of Disaster Forum, Abdul Latif Khan of NAHAB, Jasim Uddin of ADAB and Rafiqul Islam of FNB participated in the programme as experts and guest speakers.
Three co-chairs of the CCNF -- Abu Morshed Chowdhury of PHALS, Bimol Dey Sarker of Mukti Cox's Bazar and Rezaul Karim Chowdhury of COAST -- moderated the programme.
The participants urged the government to resume mobile and internet networks with 4G facilities in all Rohingya camps in Ukhiya and Teknaf of Cox's Bazar at least for the time being so that there are people's self-preparation, no rumours and misinformation, and so that Rohingyas can communicate with health facilities.
Speakers also said international agencies should consider the whole district as a host community area and awareness should be raised about social distancing.
They insisted that Rohingyas and foreigners should in no way be considered the root of the coronavirus crisis.
