调用 wx.getPhoneMask 时出现不同手机不同报错等情况，例如

fail <Error: idaas fail: -700000.request:fail cellular network is unavailable>
Error: idaas fail: -700000.request:fail cellular network is unavailable
    at Le (WAServiceMainContext.js:1:568032)
    at WAServiceMainContext.js:1:583339

和

{"errCode": -438, "errMsg": "wx.getPhoneMask fail: -438. rid: 1743404868142-E0WQrtRI"

且在调用过程中偶尔能调用成功 但是代码中完全没有改动 上周开发的期间也是一直正常
