大家好,我想請教也是中華電信的使用者,是否曾經發生過這種狀況……
在2月中之前,我覺得沒問題,從2月底到今天,儘管訊號4格到滿格,也顯示4G+,但是
4G速度卻變得異常緩慢,無論在什麼時間、地點測速,下載都在 3-5 Mbps、上傳 4-6
Mbps,我甚至去中華電信直營服務中心現場測,也這麼慘,但以往如果在直營服務中心
測,下載是可以70 Mbps以上甚至破百。
我今天還發現,如果把訊號切換成3G,滿格,下載可以10-20 Mbps、上傳 0-2 Mbps,
下載還比4G快了3倍……
昨天我跑去高雄市區一些大馬路上實測,以往4G可以40-60 Mbps,現在變成2-3 Mbps,
難以想像的慢。我已經打了N通客服了,一直沒找到原因,本來以為我G4手機太舊,但
昨天我的SIM卡拿去插在U12上測速,4G下載只有1-2 Mbps(更慘)。
客服只會做訊號重整(沒用),工程師說基地台應該沒問題,那到底要怎麼辦?目前暫
不考慮換SIM卡,我SIM卡裡存了七張t wallet行動金融卡,如果換掉,我得臨櫃跑七家
銀行重新設定,很麻煩……(SIM卡我用橡皮擦擦過了,沒有影響。)
我覺得沒道理,怎麼4G速度會突然間驟降,很不合理!Orz
