物聯網卡的應(ying)用領域(yu)非常廣，比如(ru)說在車聯(lian)(lian)(lian)(lian)網(wang)、智能(neng)穿戴、安防(fang)監控(kong)、共享設備等行(xing)業，為智能(neng)設備賦能(neng)提升自身(shen)價值。我們也知(zhi)道，物聯(lian)(lian)(lian)(lian)網(wang)卡(ka)有(you)三(san)大運營(ying)商(shang)：中國(guo)(guo)移動、中國(guo)(guo)聯(lian)(lian)(lian)(lian)通和(he)中國(guo)(guo)電信。三(san)家的物聯(lian)(lian)(lian)(lian)網(wang)卡(ka)優勢也各有(you)千(qian)秋，不(bu)(bu)過今天咱(zan)們重點(dian)回(hui)答網(wang)友的疑問(wen)“聯(lian)(lian)(lian)(lian)通的物聯(lian)(lian)(lian)(lian)網(wang)卡(ka)好不(bu)(bu)好用？能(neng)不(bu)(bu)能(neng)買？”

聯通(tong)物聯網(wang)(wang)卡是(shi)由(you)中國聯合通(tong)信網(wang)(wang)絡公(gong)司物聯網(wang)(wang)運營支撐中心負責的(de)(de)物聯網(wang)(wang)絡架(jia)構。中國聯通(tong)只(zhi)對(dui)企業(ye)客戶(hu)提供(gong)物聯網(wang)(wang)業(ye)務服務，不(bu)對(dui)個人客戶(hu)提供(gong)物聯網(wang)(wang)服務，提供(gong)車輛服務、智(zhi)能(neng)抄表、無線POS機(ji)、移動。媒體、生(sheng)產與環(huan)境監(jian)測、智(zhi)能(neng)可穿戴(dai)設備等各行各業(ye)的(de)(de)互聯網(wang)(wang)業(ye)務。

聯(lian)通(tong)(tong)物聯(lian)網(wang)(wang)卡(ka)是一種專門為物聯(lian)網(wang)(wang)設備(bei)(bei)提(ti)供數(shu)據傳輸服(fu)務的卡(ka)，其可(ke)靠性與其他移(yi)動網(wang)(wang)絡卡(ka)相比有(you)很大的優勢。聯(lian)通(tong)(tong)物聯(lian)網(wang)(wang)卡(ka)支持多種通(tong)(tong)信技術，如2G、3G、4G和NB-IoT，能夠適應各種不同的物聯(lian)網(wang)(wang)設備(bei)(bei)的需求。聯(lian)通(tong)(tong)物聯(lian)網(wang)(wang)卡(ka)還提(ti)供了穩定的數(shu)據連接、靈活的計(ji)費方式和安全(quan)的通(tong)(tong)信服(fu)務，可(ke)以有(you)效保障物聯(lian)網(wang)(wang)設備(bei)(bei)的正常運行。

那(nei)么，對比三家，聯通的(de)物聯網卡有哪些優缺點呢？

聯(lian)(lian)通(tong)(tong)物(wu)聯(lian)(lian)網(wang)(wang)(wang)卡最(zui)為突出的(de)(de)就(jiu)是資費(fei)相對比其(qi)他便(bian)宜很多(duo)，但(dan)是最(zui)大的(de)(de)痛點(dian)就(jiu)是網(wang)(wang)(wang)絡(luo)信號(hao)(hao)覆蓋(gai)有(you)(you)限(xian)，大部分農村山區(qu)都沒有(you)(you)網(wang)(wang)(wang)絡(luo)信號(hao)(hao)，這就(jiu)造成了想用不能用得尷尬局面。其(qi)次(ci)，聯(lian)(lian)通(tong)(tong)物(wu)聯(lian)(lian)網(wang)(wang)(wang)卡的(de)(de)優勢，聯(lian)(lian)通(tong)(tong)物(wu)聯(lian)(lian)網(wang)(wang)(wang)卡流量不清零，半年有(you)(you)效期用多(duo)少(shao)充多(duo)少(shao)，但(dan)是也(ye)有(you)(you)劣勢，比如網(wang)(wang)(wang)速比較慢(man)。鑒于(yu)3G和。4G之(zhi)間信號(hao)(hao)穩定性也(ye)一(yi)般，聯(lian)(lian)通(tong)(tong)物(wu)聯(lian)(lian)網(wang)(wang)(wang)卡以流量池(chi)卡為主，這也(ye)導(dao)致聯(lian)(lian)通(tong)(tong)流量卡流量渠道比較混(hun)亂，才出現之(zhi)前市(shi)面上一(yi)些很便(bian)宜的(de)(de)聯(lian)(lian)通(tong)(tong)物(wu)聯(lian)(lian)網(wang)(wang)(wang)卡，而(er)且普遍存在扣減流量的(de)(de)現象。
